Title theme:

New Beginnings


Unlike the previous OST Composing Jams, there will be no public rankings this time around, since this jam is aimed to be more relaxing and chill (although there will still be a rating period at the end to vote on your favorite submissions to be in the compilation album!) You can now also work in teams/bands of any size!

You must submit the original recording in .mp3, .wav or .flac format on AND on a streaming service of your choice (preferably Soundcloud), with a screen recording or screenshot(s) or pdf of your DAW, score, or tracker. (This is to prove that you are the original creator)

There are three types of tracks you can submit:

*Please only cover songs that has an official audio-only release in the US (this only applies for covers and medleys), otherwise we cannot license the songs to be released in the compilation album. — PLEASE DON’T WORRY TOO MUCH ABOUT THIS FOR NOW! Tribute songs can be from any game regardless of the soundtrack's release region. You can use to look this up. Everything submitted must not contain any copyrighted samples.

Listen to the previous jam's top submissions!
