I have not heard the Herb Alpert, Jill Switzer or Dreams of Ibiza by BIckley Rivera either
I've heard and recorded "Dreams of Ibiza", but only a 90 sec. cut of it.
I have heard the Herb Alpert song at least once. I think I heard it after Storm Stories or something like that. The problem is exacerbated with the long-form programming on weekday afternoons and especially on weekends from the afternoon until the overnight hours. You'll only get to hear 1 min of the songs play, not even on the 8s!!
I think that is when some of these unheard songs play. The rotation needs to be tweaked very much, because there are a lot of quality songs throughout the playlist that should be played, but they are not. For instance, all I hear during most of the times I have turned during primetime is Magnificent Eleven, Eminence Front, and Diamond Eyes.
