Whenever I start a shuffle play on a playlist, the shuffle looks normal in the queue -- but if I keep moving back to the previous songs, they are almost all by the same artist until after about 20 or so songs when it goes back to a normal shuffle. This happens on both my laptop and my phone, and it only happens with one artist: Paul Jones. This carries through any playlist I make with his songs in it, and doesn't happen in playlists without his songs. This also happens in Songs but much less severely, with at most 4 or 5 songs in a row being from Paul Jones.
