BeemerBoy:
Thanks a lot for answering that question, it always perplexed me too.
I don't know very much about music that is stored in any other format than a compact disc, and the first time I ever tried using a music file (MP3 file) on my computer was when the 2820 arrived in March and I was trying to figure out how it worked.
What I discovered (stumbling around in the dark) was that playlists with the extension .wpl didn't seem to work, but playlists with the extension .m3u did work. The problem I still have is that I have no idea how to make a playlist with the extension .m3u on the end of it. The music player I use (Windows Media Player 10) seems to only be able to make playlists with .wpl at the end of them.
Something else I observed by stumbling around - the GPSR does not appear to list playlists that are 'nested' in folders. For example, if the heirarchy of music folders inside the GPSR is 'music' / 'oldies' / 'singles', the playlists buried three folders down in 'singles' didn't show up on my GPSR.
May I trouble you to perhaps provide all of us 'music newbies' with a beginners guide to things like playlists, album art, stuff like that? I would sure be grateful for an overview of the subject.
