How I found out about this song:
1) I was watching "NOVA", a show on the Dutch channel VARA (via the internet), and they showed some kind of environmental rally in Westerpark in Amsterdam that seemed to coincide with Live Earth (I don't speak Dutch), and they had a brief clip Jeckyll & Hyde (a group I've never heard of) playing an AWESOME song
2) I look up Jeckyll & Hyde on Myspace, the song happened to be "Freefall"
3) I click the video on their site, which leads me to Youtube, or something like that, and I stumble upon that song.
So yeah, I know about Jumpstyle...and I love it! I don't see why no American CHR stations play it. Once in a rare while, instead of "Party Like a Rockstar" or "Pop, Lock, and Drop It", put "Freefall" on. I'm sure the kids will like it. Or even "Hey Jumpen" for the shock value.
