I haven't heard it on the radio yet. I rarely listen to mainstream music radio anymore.
Same here, but I've put up with Cleveland radio the past few days, just to see if I could catch it. Still nothing - although - 92.3 WKRK is playing an intro:
"Hey this is Scott, Eric, Dean, and Robert, and we are Stone Temple Pilots. Listen to our new song, Between the Lines, right here on WKRK Cleveland!"
I've heard the intro twice - both times, going right to commercial afterwards. Haha.
