Equalizer keeps going out on me?

[spaceoutlaw]

I'll be listening to music with my equalizer settings on, and all of the sudden the equalizer will go out and the music will suddenly become much louder due to my equalizer having a lot of bass and being a having th let tube amp setting on. Does anybody know why spotify keeps doing this? It's really annoying and it takes maybe 3 minutes until the equalizer will come back again. It hasn't always done this and I've been using spotify for about 8 months now.
