I've been using Suno (I have no idea how it compares to Udio) to write daft lyrics then turn them into songs. A friend and I are having a right old comedy tennis match sending each other mad songs. It's bloody great! I don't really look at it as making music though, just a fun computer game.
I just do it on my phone from the site, not via an app. Takes about 10 minutes with hilarious results.
