Any way to mod guitar hero?

hi, i used to use horizon alot for the easy way to mod and swap saves. the question im here for is, is there any possible way to get custom songs on any guitar hero game? im looked at just about every forum, and they all say you need a different console or a modded xbox. i know you can do it on rockband 3 but i cant find the game and if i do im just gonna switch to that completely.
