I've seen hundreds of research projects in every AC format variation, market and company. They all say that listeners want to know the title and artist. Also seen research with those song tags on AC around the US. Some very positive, some very negative. In a "me too" business, when B101/Philadelphia does something, every AC that isn't winning(and some that are) copies it. Unfortunately, they are more apt to copy the IDEA, and blow off the precision execution that makes the idea work. Eventually, the smart ones do what works for their stations. The others punt, or in this case, settle for mediocrity. And everyone, except Jerry Lee, forgets that B101 funds low 7 figures every year for marketing. They used to standout when everyone was marketing on TV. Now, they really stand out as no one else spends any marketing money.
AC is winning big in many major markets like NY, LA, SF, Philly, Houston, DC, Miami, etc. PPM helps because it eliminates phantom cume, which was ACs biggest enemy in diary recall. Most of these stations don't use those song tags. Most have either tried and abandoned them or researched the concept to find it was as annoying to the listener as it is to all of us. If any doubt existed, they didn't implement it.
On Q92.9, you have pretty good talent, including the new guy, Jim. Those song tags aren't necessary, in my opinion. They cause so much format flow clog that having live or even tracked talent mention the song is much more effective.
Then when you couple those song tags with the Lynn Hoffman lifestyle liners (or whatever they're called) whose content and horrid execution (often all over vocals) the sound becomes a mish-mosh. Two reasons folks are probably going to Star, Wish, B, 3WS, etc.
I don't really get what the hoopla about changing to Hot AC is all about. It's still a mid pack, at best, AC station surrounded by other, more potent AC stations.
