I use my phone a lot while driving, that is, have the car dock, and I listen through Pandora. I use the free version, which has annoying ads. I swear I'm going to cause an accident one day trying to get rid of the ads once in a while. Anyway... I'm not very well sold on the audio quality. Granted, my setup isn't the best, either. It is connected through a tape deck adaptor. My stereo does not have an AUX port and does not support Bluetooth. That said, I was wondering if anyone here knew of a good audio mixer, so I can fine tune the sound when I play rock music (specifically heavy metal, glam rock, hard rock). My old Omnia phone, I can't remember what application I used, but I was able to customize the sound for a specific type of music, which was all preset. I'm looking for something like that, or something I can tweak further.
