This week saw the release of new imports in the music store, and it's a handful of stuff from GH Metallica! All of their songs (minus "All Nightmare Long" which was already DLC anyway) and about half of the guest songs were transferred over, and I guess it'll be more fun to sing them when there's 100% less freeforms now. Here's proof that it works, on something that really challenges the guts of my throat.
Thanks :D
