In this game you're allowed to actually create your own songs, but the song builder is very limited. I spent like an hour crafting a song, and in the end it was complete garbage. Plus not like that has any actual impact on the in-game quality of the song and how it will be received. They should've either used existing songs or made them symbolic and cut the rhythm-game sections entirely. I'd rather see something like in Game Dev Tycoon where you select the genre and other aspects of the song and then your character skills determine how it turns out.

You are allowed to not craft songs manually, which also obviously removes the rhythm-game, but then songs become just abstract names that don't represent anything.

Also, I recorded a bunch of songs and wanted to put out like an EP, but I couldn't figure out a way to do it. Perhaps you're not allowed to until you get a record deal or something, idk, but that's stupid.
