I was listening to my local Clear Channel mainstream AC station today (WSRW/Grand Rapids) and heard the song "Without You" by David Guetta and Usher. I guess it's part of CC's Premium Choice package.
Anyway, I was quite surprised to hear that song on a mainstream AC station. Supposedly it has charted somewhat high on the AC chart, but it just seems strange. It's a great song, but it illustrates the point that the lines are continuing to blur between Mainstream/Hot AC and CHR.
I had to do a double take this morning when I was listening to that station. At first I knew I'd tuned in to WSRW but then doubted myself - thinking I was actually listening to one of the CHR's instead. LOL
The song fits very well with what AC is today.
