general question about music players on moment/android

OK, so I've had my moment a while, use it regularly as my main mp3 player too since the battery on my archos 605 won't hold a charge anymore. I'm happy with the mp3 player, it does what it's meant to do. Only thing is i wish there were an EQ of some sort but I only found 1 media player app that had 1 and it sucked (EQ was amazing, media playback was awful).

I did read in 1 forum someone commented "why are you even still using the stock media player for mp3s?" as a response to a question about the media player. Which raises a question for me... Why not? What do other media players (primarily for music) do better than the stock player? I tried a few and felt like they didn't do anything much differently than the stock 1 except had a little more web integration. I can't remember the 1s I tried though. Maybe I just haven't tried the right 1? I think 1 I did try was meridian (heard it mentioned a lot) but again didn't see too much different/better about it besides the interface.

Thanks for feedback

Is this one of those programs that once it expires, you can uninstall it and reinstall it and it will continue to work? Or perhaps uninstall just before it expires and reinstall the full 30 days again? Not to sound cheap
