Besides every single genre of music, the grammy also awards:
Best Zydeco Or Cajun Music Album
Best Rap Solo Performance
Best Album Notes
Best Historical Album
Best Boxed Or Special Limited Edition Package

The list is actually very extensive and impressive... much more worldly than what they show tv. Anyway, guess what won best boxed or special limited edition package? In rainbows, of course!! haha. Thom Yorkes performance at the grammys looked strange to me... He got some jonas brother haircut and danced exceptionally enthusiastically. Is he always like that?
