Stations can call themselves whatever they want. Nielsen still lists them as Rhythmic Contemporary.Today I noticed that KPWR's wikipedia page lists the station as "Rhythmic Hot AC" now that they've been playing a lot more throwbacks in the last year or so.

Is this true? Is Power 106 no longer "Rhythmic" and is now "Rhythmic Hot AC"?
Of course, Meruelo and their operations manager parted company before the holidays, so there may be changes going on over there.
