I use my SmartPhone to listen to MP3 content every day - music and spoken. My beefs with the Microsoft Media Player are:
1. Takes an age to fire up - I presume it scans my entire 256meg SD card for content every time it runs.
2. It often stutters during playback (doesn't seem bitrate related - 32kbit spoken content or 160kbit music is equally effected),
3. It doesn't save the playback position when you leave the application - half way through an hour long radio programme and you're stuffed!
4. No jog/shuttle within a file (see note 3!)
5. If you receive a 'phone call when listening it quits the application (see note 3 and 4!),
6. No eq.
7. No playlists.
8. It slows the 'phone down so that other functions are unusable while it is running - can't compose emails etc.
PocketMusic suffers none of these inadequacies and is free! get it here.
Oh, it also supports WinAmp skins (hmm - not top of my agenda! I'd rather a command line interface!).
That URL was wrong - now it's right!
