Since [[Update 1.9]], instead of using the soundtracks used in main levels, there is the option to download other music from the [https://www.newgrounds.com/audio Newgrounds Audio Portal].

Since [[Update 2.2]], instead of using the soundtracks used in main levels and the [https://www.newgrounds.com/audio Newgrounds Audio Portal], you can use 6000+ songs in a music library, from Nocopyrightsounds(NCS) and from other creators.

If a Newgrounds song is completely verified, it can be used in the game. To do so, you must select the gear button in the top right corner, select the "Custom" option, and then type in the ID of the desired song. To find the ID of the song, you can find the song on Newgrounds. They then must download the song and click the Use button, which will use the song in the level. Anything that pulses to a regular song (such as rings and certain decorations) can also pulse to a custom song if there is a clear beat. If you have downloaded a song, you can also click the saved songs button to quickly use a downloaded song in your level. However, there is a limit to the number of songs you can have saved. Despite this, in the options menu, there is an option to remove this limit.

In the custom songs menu, there is a gear to change the start offset, playtest the music and make the music fade in or fade out.

There is a guideline editor that creates guidelines for the song. You can again put the start offset, and you can record the guidelines. You can clear them using the Clear button.

====Whitelisted artists====
When custom music was added to the game, many people uploaded others' music to their Newgrounds page in order to use specific tracks. They then forced others in the community to scout them (Newgrounds' system of verification for allowing users to upload their songs to the audio portal: more info can be found [https://www.newgrounds.com/bbs/topic/1318101 here]), and Newgrounds moderators spent hours of their time deleting these songs. To address this, an internal whitelist of artists whose music would be allowed to be used in the game was created. Prior to March 2020, only the developer could add artists to the whitelist, where now elder moderators can also add to the list.
