Worse is that the missing stuff is constantly shifting. I'll add a whole album (worth of songs) to a playlist, and a few months later one of them is grayed out but the rest still work. The Spotify forums seem to suggest this is because someone licensed that one song differently and conditions have changed, so I'm no longer entitled to play it. That seems bonkers to me, but regardless of the reason, the effect is infuriating. I ditched Spotify a while back and I'm slowly clawing my way back into physical CDs, ripping and encoding (or not even bothering to encode; storing as plain WAV still doesn't take that much space given modern hard drives), and trying to ensure that songs don't vanish out from under me ever again.
