I'm noticing an intensifying trend on Hot AC stations. There are several exceptions, but it's seeming more and more like for a track to hit top-10 (or even sometimes 15) on Hot AC, it has to be a massive or at least decent CHR or Alternative hit. Katy Perry, Justin Timberlake, Bastille, Lorde, Pharrell, John Legend, Paramore, and such that are making up the top 10 on Hot AC currently are/have been big CHR or Alternative hits.
The current highest peaking more "typical" Hot AC tracks, that aren't really crossing over and have limited potential to do so, like Ingrid Michaelson's "Girls Chase Boys", Sara Bareilles' "I Choose You", and even Christina Perri's "Human" are going sideways, and seem to have limited potential to advance up the chart compared to more CHR-friendly artists. They're being shut out from higher positions on the chart, or surpassed by up-and-coming CHR hits from blockbuster artists that skyrocket up the chart. There are a lot of adult artists commonly in the upper teens and 20's on the Hot AC chart, but they rarely become hits because they haven't been huge CHR or Alternative hits.
Anybody else feel like it's getting harder for MAINSTREAM adult-oriented artists to achieve success on the format if they haven't already done so on CHR or Alternative? Why can't the Hot AC format have any original material anymore? There have been a lot of great, Hot AC-friendly tracks in recent years that have had limited to no success due to the fact that they weren't mainstream, well known artists.
