When I shuffle all, either recently played or my whole library I'll get to a point where 5-6 songs will play over and over. My library on my phone has about 2200 songs in it. I'll be at the gym and a song will come on again followed by a few more of the songs I already heard. If I skip to the next a half dozen times, I'll get a song I haven't heard yet. It's really weird. Anyone else get this?
