Sent from my Nexus 4 using xda app-developers app
Hey mate, not sure you're in the right place? It says you sent that from a nexus 4...
Anyway, I find that music playing drain is dependent on the music player itself rather than the ROM. For example, for me, doubletwist used approximately double the battery usage per hour as Apollo music player. Have a go with a few different players, if you're concerned with battery then find a minimal player and test.
