Let's face it, Oldies and Classic Hits are going through some changes these days, as are AC stations. It appears everybody's trying on new clothes that don't always fit or look good. Rarely do 56 year old guys look good in Speedo's. Rarely do 56 year women look good in low cut gowns. Gravity is a vicious equalizer, ain't it! Enough of the metaphors.
WSEN is a pretty good Classic Hits station, but it sounds clunky at times. I hear it as I drive through Syracuse. It's very listenable, but its formatics aren't as smooth as, say CBS-FM, WOGL Philly or what used to be WHTT (before it turned into AC-Gold hybrid Mix 104) in Buffalo. It seems to have a 70s feel to it, which is the sweet spot for Oldies-Classic Hits stations. Keep in mind that I listen to it only about 75 minutes at a time, while you locals hear it every day. I'll concede there may be a major difference in perspective.
I too think it's a big mistake for Classic Hits stations like WSEN to play too many 90s songs, but a friend in the business has an interesting perspective. He says it's all about sound compatibility. Songs like "Kissed By A Rose" may--- I said may--- fit the format by virtue of sound. Not sure if this particular song is a good example.
I can tell you what songs definitely don't fit the Classic Hits format: Boogie, Ogie, Ogie and Disco Inferno, Waterfalls by TLC and a few others that stick out like sore thumbs. The truth is, women in a certain demographic love disco. I have nothing against disco hits appearing on Classic Hits stations, as long as they're legitimate radio hits (e.g., Rock The Boat, Brickhouse, All Night long) and not club hits.
Classic Hits programmers have to be very careful that they don't poison the format as they attempt to bring in younger (35-44) listeners. In many markets, especially in the Northeast, successful Classic Hits-Oldies stations perform better if/when they add rock-based 80s songs, e.g., Bryan Adams, "Summer Of '69" and Mellencamp's "Pink Houses" and Springsteen's "Born In The USA." These songs were big hits and they're mass appeal. They're also 20+ years old... let that thought sink in.
BTW, "Let's Get This Party Started" by Pink may be on Y-94 in "weekend-only" rotation. It was a bona fide hit and chicks dig it. It's a staple in normal rotations on Hot AC stations.
