Christmas Present Ideas?

Ok, so, im gonna be one of those sweetheart boyfriends who wants to get a little something for his girlfriend. Thing is, im at a loss to what i want to get her. She likes this band named "Akaline Trio" and she pretty much knows the band and has a sweater of them. And, being a band i havent heard of till the day we met, there is none of their stuff in stores anywhere near my house. So, ya, i dont think im going to get her anything of the band. She really likes music, games, and drums. So this is begging the question..... what should i get her for Christmas?
