A lot of the music I listen to on spotify seems to suddenly be saying "this track in not available". To give some specific examples some of these albums are. Ben Howard "I forget where we were". Aphex twin, loads of stuff, but "druqks" isn't there. Radiohead, lots of stuff, "In Rainbows" for example. There are quite a few artists other that this who are down. At the same time a lot of stuff is still up.
Is this spotify's problem or is something going on my end?
