How to Add Custom Songs in osu! (Easy Guide)

The Ultimate Guide to osu! Custom Songs and Beatmapping

If you have ever spent hours clicking circles to the rhythm of your favorite track, you already know the magic of osu!. But what truly keeps the community thriving year after year is its endless supply of custom content.

Whether you want to play tracks from indie games, anime openings, hyperpop bangers, or classical masterpieces, custom songs are the lifeblood of the game. Let’s dive into how custom songs work, how to download them, and how you can even create your own.

What Makes a “Custom Song” in osu!?

In standard rhythm games, you are usually restricted to a fixed tracklist chosen by the developers. In osu!, nearly everything is community-driven.

A custom song package—known as a beatmap—consists of:

• The Audio File: Usually an .mp3 or .ogg file of the track.
• The Background: An image or video that plays behind the action.
• The Hit Objects: The circles, sliders, and spinners meticulously placed by creators to match the vocals, drums, and melody.
• Difficulties: Most custom songs feature multiple tiers, ranging from “Easy” for beginners to “Insane” or “Expert” for finger-snapping pros.

How to Get and Play Custom Songs

Adding new tracks to your game is quick and straightforward. Here are the most common ways to expand your library:

1. The osu! Website (Beatmap Listings): Head over to the official osu! website, log in, and browse the massive beatmap listing. You can filter by genre, language, and game mode (osu!standard, Taiko, Catch the Beat, or osu!mania). Clicking “Download” gives you an .osz file. Double-clicking that file automatically imports it straight into your game.
2. osu! Direct: If you have an active supporter status, you can use the built-in osu! Direct browser right inside the game client to search, preview, and download custom songs instantly without ever opening a web browser.
3. Beatmap Packs: If you want a massive injection of music all at once, the official site offers curated beatmap packs grouped by theme, artist, or year.

Step into the Editor: How to Make Your Own Beatmap

Ever listened to a song and thought, “This drop would make an incredible slider section”? You can turn any track into a playable map using the built-in osu! Editor.

• Step 1: Set Up the Audio. Open the editor, drag and drop your chosen MP3 file into the game, and create a new beatmap.
• Step 2: Map the Timing. This is the most crucial step. You must align the game’s internal metronome (BPM and offset) with the song’s actual beat. If the timing is off, hitting notes will feel frustrating and unnatural.
• Step 3: Place Your Objects. Use the compose tab to lay down circles, sliders, and spinners. Good mappers sync their objects to meaningful layers of the music—such as matching circles to vocals and heavy drum kicks to sliders.
• Step 4: Test and Polish. Playtest your creation repeatedly. Adjust the spacing, tweak the difficulty settings (approach rate, overall difficulty), and add a cool background image to set the vibe.

Why Custom Songs Keep the Community Alive

The beauty of osu! custom songs is that anyone can contribute. Because the library is entirely crowdsourced, it acts as a massive musical time capsule reflecting internet culture, anime trends, and underground music scenes.

Whether you are downloading a chart-topping meme song or spending weeks timing a complex progressive rock track, custom songs ensure that osu! never feels stale.
