So I've been using this Pro Player the last 24 hours - it's pretty good. Much better than stock, but the sound I'm getting from Poweramp still far exceeds what Pro Player is offering. And while parts of the interface are nicer than Poweramp, I still do prefer PA over PP. I will give it another couple of days, try and tweak some of the settings but it's not different enough (or improved enough) for me to spend any additional money on a music player when PA does the job very well.
On another token, I was running CM7 and then CM9 on my DX prior to buying this phone. One of the settings in CM gave you the ability to have text and email notifications play OVER the music, rather than stop the music entirely and then go back to it when the tone was done. Is there any way to do that with this phone or is that a mod not included in the stock software?
