i bought it. it gets my gf to play the game and got her to pay for it. but the song, "burn it to the ground" is actually pretty good on guitar, really fun on vocals(especially if you add in the plethora of curse words, although some made it in anyway. bass is meh and drums....well it plays but its really easy.
as a guitarist primarily, I can say it is semi challenging(lots of ho/po's which can mess up all but the best players) and the solo is ok. all in all, if your on the fence, i'd say get this song and forget the rest.
