I ran GMMP through the emulator in 4.4 and didnt see any major issues.. so I set the target sdk to 19 (4.4) for this update.
-Updated for Android 4.4 KitKat
-Fixed another silent crash that could occur when changing tracks with the equalizer enabled
-Fixed crossfade issue where GMMP would crossfade into the second track instead of the first when selecting a new album/folder
-Updated Spanish translations
