Couldn't about anything do better than FM100? Streamed them the other day and was not impressed. I think Entercom could certainly do more with country...
While I tend to agree with you that FM 100 isn't overly impressive, I heard a couple of years ago that it was a top-3 biller in the market among "non ethnic" targeted stations. Of course, that was before Prestigiacomo, 1/3 of the morning show, and the night show were let go. So, it's possible that could have changed. However, I still don't think it's likely you'll see Entercom toast FM 100.
Memphis should be going PPM very shortly, and PPM has been very good to hot AC formats. WTMX in Chicago has seen some of its best ratings in years since PPM went live, and KYKY in St. Louis saw its audience grow 300%. Houston, Boston and Detroit have also seen good results for hot AC.
