Here is a quick flashable mod that you can use on any AOSP Rom. This mod will work with any of the following just to give you an example CM, AOKP, Paranoid Android, Pacman, Team Baked, Team Toasted and more. This Mod brings the beats audio app to your phone. This is like an equalizer and will give your audio a more premium, bassy sound. This installs via the aroma installer, and you will need to type a few simple commands in terminal emulator once the installation is complete. Other than that this couldn't be much simpler!
Sadly no, not yet I believe at one point on XDA he said he was going to try that, but so far it's only a flashable mod.
I love this, I've been using it since like v.3, and it really cranks up the bass! The instructions are little more intense than most mods, but one package for so many devices, I understand it would be needed.
