Spotify is playing too fast. I think it is about 20% to 50% faster than normal.
I have uninstalled and reinstalled Spotify, and I updated QuickTime. It is still playing too fast.
Windows XP, sp3
Jukebox plays at normal speed. Spotify worked fine for two weeks before the fast playing started.

Try disabling "Enable Hardware Acceleration" in the preferences and play your music again. I've had this before, and I'm sure this fixed it.
If you've just started using spotify and its been doing it all the while, make sure your computers audio settings are set to play at 44,100hz rather than 48,000hz as this would cause a significant speed up
