What should I buy a 15-year-old German boy for Christmas?

He’s my host-brother who I haven’t seen in three years, and haven’t really spoken to much since then either. But I always send the family Xmas presents and have found something for all of them, but him. He likes PC gaming kind of stuff, but I don’t think it’d be a good idea to get him a game that’s only in English because, although I know his English has improved since I last saw him, I still don’t know whether he would enjoy/understand something entirely in English. He also listens to a lot of music, so I was thinking maybe a base thing for an iPod, or a CD of an American reggae/hip hop artist (he likes the Black Eyed Peas and Seeed—German band), if anyone knows an artist of the genre. I’m trying to keep it under $30, if possible. Any suggestions? Thanks!
