spotify app continually access network by data connection when phone enter sleep mode

[arimatech]

Dear developer,
   We download the Spotify(Android version:3.0.0.1124) from market and login, and listen to some music for a while,then pause music, and go to Home Screen and enter sleep mode by pressing power key.
   We find the spotify app continually access network by data connection when phone enter sleep mode, such behavior will cause the phone increase power consumption much more.
   Could you please fix this issue?

If you are on android ICS do the following:

System settings --> Data usage --> Set mobile data limit (tick this) --> find spotify in the list in the lower end of the data usage screen --> press it --> on the spotify stats scroll down and restrict background data
