When did XM Kiss 21 (X021) Join Mediabase CHR?

... because it has some monster spin totals I never noticed before:

1 FLO RIDA Right Round 179
4 KELLY CLARKSON My Life Would Suck Without You 175
3 ALL-AMERICAN REJECTS Gives You Hell 174
4 LADY GAGA Poker Face 170
5 T.I. Dead And Gone f/J. Timberlake 170

Could just be I never saw it, but wow that's a big influence on the panel.

They also added Pitbull this week- went from 0 to 69 spins. :o

I think it's new! I just saw it a few days ago for the first time. WOW @ those spin counts! :o

The gap between 5 and 6 is huge!
1 5 T.I. Dead And Gone f/J. Timberlake 154 181 -27 0.364
7 6 BLACK EYED PEAS Boom Boom Pow 80 80 - 0.190

^Dunno I almost think it's kinda unfair to include stations that spin songs THAT much (i. e. 154 or 181 times a week) cause it basically makes that station literally "count" twice as much as other CHRs (even though they're almost always catering to an audience that only tunes in for an hour a day on average...hence the ridiculously high spin counts)
