I'd like to know the artist and title for songs in the playlist of the
xbox snowboarding game "Amped". I am only interested in the songs
appearing under the following in-game genre labels: "EMO",
"Electronic" and "Hip-Hop", but I can isolate these myself from a
complete list.

Hi there!
You can find a complete listing of all the songs on the "Amped"
soundtrack on the Xbox.com website here:

The genres are nicely seperated for you on the site.

I wish I had a search technique for you, but I just knew where to go
as I'm a huge Amped and Xbox fan myself.

Thanks and I hope this helps!

Perfect answer. I can't believe I didn't find that myself - d'oh!
