Not only will 152 of the 158 downloadable tracks already work with Guitar Hero 5, but you'll also be able to import "some" of the Guitar Hero World Tour and Smash Hits tracks as well. Of course, there will be a fee involved, just like there was with Rock Band, but for once, it's a fee we wouldn't mind paying. All of the songs you import will feature upgrades such as band moments and vocal star power.
I Think This Is Great now that you can import music I dont know about you guys but i think i might get into the Guitar Hero series and Give Rock Band A Break
