I just got an email from PocketMind (I didn't realize I was signing up for a newsletter) saying that there's a new version of PocketMusic out. Here's the improvements:
1. Map Volume Up/Down in free version.
2. Improved Shuffle Algorithm (<-- This is why I wasn't using it)
3. Ability to sort songs in playlist by track number from ID3 tags.
4. Support of quick rewind for big MP3 files.
Also the feature pack that you buy has this added feature:
1. Support for WMA files.
I don't really care about WMA, but I know a lot of people do and this should be big for them.
