I am currently using Conduits latest version of PocketPlayer (3.5).
It is a great audio player, with great functionality like pulling album art from the web, fullscreen album art, streaming podcast and internet radio (shoutcast). It also has finger friendly controls, utilizing a touchflo type interface for the library.
I was a devout WMP user before this release, but I'll be happy to pay the $20 when my 30 day trial of PocketPlayer is up.
You can download it a trial from
