Albums, EPs, LPs, CD singles what Does it all mean

When talking about music, various physical and digital media are referred to in different ways. All these different labels help consumers understand the difference in what they are listening to… but what do these common terms mean? Albums, singles, EP’s, LP's, and CD singles… What are they, and why do we use them?

A big reason these words stick around is that music culture has always been tied to formats, from vinyl and cassettes to CDs to downloads and now streaming. Even when you are listening on Spotify or YouTube, the language still helps you quickly understand the size of a release, how it is meant to be consumed, and where it fits in an artist’s bigger story.

Starting off with the most commonly heard one, albums. Albums are long forms of music, often being seven or more tracks with a run time of 30 minutes or more. These are made by musicians, and tend to be most artists' main focus. Albums are what gain the most traction with the public, and tie all these other terms together. A great example of a popular album is Rumours by Fleetwood Mac, or more modern, Short n Sweet by Sabrina Carpenter. Albums are the industry’s standard, and it’s what’s used most.

Albums are often designed as a complete experience, with track order, pacing, themes, and even artwork working together to create a “world” around the music. They also tend to be the release that gets the biggest marketing push, like tour announcements, major press runs, and long rollout campaigns. You will also hear people talk about standard editions, deluxe editions, and reissues, which are all still albums, just with extra tracks, alternate mixes, live recordings, or bonus content added later.

CD singles are releases containing one or two songs. The main goal of CD singles is to help promote albums, and gain more radio plays for artists. CD singles help fans understand what an album is going to sound like and what the artist's vibe is going to be for their upcoming era. SInges also benefit artists in more ways than streams. CD singles help musicians stay present and known in their genre in between album cycles.

Traditionally, CD singles could include an “A-side” main track and a “B-side,” which might be a bonus song that is not on the album, a remix, or a live version. In the modern streaming era, CD singles can still exist physically for collectors, charts, and fan culture, while digitally a single might come with multiple versions like radio edits, acoustic takes, sped-up versions, or collaborations. CD singles are also a big part of chart strategy and storytelling, because choosing which song leads an era can shape how the public understands the whole project.

Extended plays, also known as EP’s, are commonly between 3-8 tracks and do not exceed 30 minutes. EPs sit in the middle ground between a single and an album, and they are often used to introduce a new artist, test a new sound, or bridge the gap between bigger releases. They can feel like a snapshot of an era rather than a full novel, which makes them perfect for experimentation or for telling one tight, focused story. Some EPs are built around a concept, like a seasonal vibe or one emotional theme, while others are more like a curated bundle of songs that fans will still treat as a “mini album.”

The term LP is an abbreviation for long play. A long play is, essentially, another term for an album. LP’s are mostly used when talking about physical media, though it still means the same if you were to use it while discussing digital media. Long plays tend to be made on your average 12 inch vinyl, and are longer than EP’s

The LP term comes from the vinyl era, where “long play” referred to 12-inch records designed to hold a longer runtime than earlier formats. That history is why you will still see LP used a lot in record store listings and collector spaces, even when the music is also available digitally. In casual conversation, album and LP usually mean the same thing, but LP often adds that extra hint of physical format, vinyl culture, and the idea of a full-length body of work.

CD singles, while not fully defined above, are worth calling out because they are a format rather than a release size. A CD single can contain one track, two tracks, or a small bundle of versions, depending on what is pressed onto it.

CD stands for compact disc, and it became one of the most dominant ways people bought and played music from the late 1980s through the 2000s, which is why so many music terms still feel “CD shaped” even today. For collectors, CD singles are still loved because they are physical, relatively affordable, easy to store, and often come with booklets, lyrics, credits, and artwork that make the music feel more tangible.

Cassettes are another format that has come back into music culture, especially in indie scenes and for limited edition drops. A cassette can hold an album, EP, or even a single, but it is usually used for full projects or collectible releases rather than quick radio promotion.

Part of the appeal is the retro, DIY feel: cassettes are affordable to produce in small batches, they look cool on a merch table, and they often come in fun colours, transparent shells, and handmade-style packaging. For fans, they feel like a personal, nostalgic object, and for artists they are a way to offer physical music without the higher manufacturing costs of vinyl.

7" records (seven-inch vinyl) are one of the most iconic “single” formats, and they are usually associated with one main track on each side. This is where the language of A-sides and B-sides really comes alive, because a 7" often literally has a song on Side A and another on Side B.

7" releases are popular for collectors because they are small, punchy, and often limited pressings with exclusive tracks, alternate artwork, or special colour variants. They are also tied to music history, especially in rock, punk, pop, and soul scenes, where 7" singles were a main way fans discovered new songs before full albums became the default.

Once you understand these core terms, it gets easier to spot what a release is trying to do. Albums and LPs tend to be the big statement, EPs are the middle-sized creative drop, and CD singles are the spotlight moment that introduces a sound or keeps momentum going.

And at the end of the day, the format is just the container, but the language helps fans, stores, and platforms describe the experience clearly. Whether you are holding a CD single, rewinding a cassette, flipping a 7", or pressing play on a streaming app, these labels are still the quick map that tells you how big the journey is about to be.
