LightPlayer

This is the most popular Java MP3 player for Motorola E398.
It have ability for managing playlists
(something missing in the 373 firmwares compared to the stock 372 in the default sound player)
and also it have the great option for configuring custom skins.
It fully supports the ROKR filesystem.


Another option that you will most probably need to pay attention is the Menu
> Types option where you can add/delete media filetypes!
