Device: Motorola Defy (MB525), running Android ICS (4.0.4), CyanogenMod 9-20121116-NIGHTLY-jordan

Issue: Whenever I'm listening to songs on any song app, If I press either volume up or down keys when the screen is on, it works fine. However, if the screen is turned off and I press volume keys, it either returns to the beginning of the song (on vol down) or skips to the next song (on vol up).

Apps affected: This behaviour is verified on Google Play Music, Doods Music Streamer, and pretty much any app that has support for skipping songs while the screen is locked.
