I've actually been planning on making a specific list of all DIY stem songs in RB4 on LR, but I honestly don't know where it would go. I believe this list to be near 100% accurate, as I have literally gone through every RB4 era song and tested to see if they were DIY or not, but there have been a few I'm uncertain of without ripping them.
I'm also planning a megapost for DIY material soon. Instead of posting individual songs, I'm planning on putting all DIY songs into a huge thread so you don't have to waste multiple credits on material that doesn't fully deserve it, so be on the look out for that.
Edit: Made a post, and you can even download anything already released!
