I'm not sure if anyone else has experienced this error, but I deal with it at least two or three times a day. After long periods of use in the web player, I've noticed that the web player will start to crap out on me. I'm talking like, 4-5 hours of continuous use, but the problem exists. This is a daily occurence for me. I'll get into work, log in to spotify, and sometime around midday the web player begins to act... weird. Slow loading pages. Failed loading pages. Music ceases to play, or album art starts to lag. Pause/play begins to be delayed, and track switching is also extremely delayed. I don't know if this is even an issue that someone would want to look into, but I wanted someone other than myself to be aware of it, if no one else is. In order to get the web player to begin acting properly I have to completely shut down my browser and re-open. A refresh just doesn't seem to do the trick. This is not a game breaking issue, of course. More just a peculiar annoyance that I wanted to get out into the public.
