Can anyone recommend an audio player that is able to combine tracks from two or more play lists. To be more specific I have a 1200+ and growing play list that is arranged the way I like (Lets call this play list A). However every year before Christmas comes I would like to mix in some holiday tunes (play list B) at a specific rate. For instance after Thanksgiving for every 25 tracks from play list A play 1 from list B and then each week be able to increase the frequency of the B list tracks.
I could also see using comedy tracks as the B list during the rest of the year.
