1. I've had the issue this fall that sometimes when selecting a song manually, playback will halt. After that no songs can be played. Closing spotify and restarting it will make it work again, even the failing song.
2. Recently, when selecting a song manually, quite often it will play back for 2-3 seconds, then pause for a few seconds and then resume again.
Both these seem to happen when I select songs I have played a long time ago, or not at all. Maybe this is a server side caching issue? I've tried to search for people having similar problems but to no avail.
