I have the free version. Until today it has been just about adequate. I don't get why albums are shuffled and other songs played in amongst the album tracks, and I hate that my 150+ playlists have the same 20 tracks played in the same order very very frequently, but the last straw has now arrived. Today I started getting 2 or 3 ads after every track played. This is infuriating. If it continues I am going back to YouTube.
