Comment 1 for bug 117281

Try the following:

Create a file called: .is_audio_player

>nano .is_audo_player

Add the following lines (modified for your situation):
#Cheesy audio player recognition script
audio_folders=MUSIC/,Podcasts/
folder_depth=2
output_formats=audio/mpeg

Copy to the root directory of your player.

cp .is_audio_player /media/mycreativeplayerthatisgivingmefits

Connect and see what banshee says.

>bansee --debug

It works for me using gutsy, banshee 0.13.1 and an old sandisk 1 GB mp3 player.

Only the folders referenced in your .is_audio_player file will get indexed in banshee, then you can play them from the player or drag them into your library, or create playlists, whatever.

Marking incomplete pending these tests.
