iPod How can i add a new song to an existing artist on ipod?

That's basicly what the playlist is for, so you can group songs the way you want to for playback. So if you get a new song and you want it in a certain playlist, you have to add it yourself.

As far as managing your artists and their collaborations; I have had this problem too. You can change the artist name to fit your search / file criteria. That will at least organize your artists. You will always have to manually manage your playlists though.

Hope this helps.

Yes, of course you can, although you may have to do it manually by creating a playlist into which you put all of the songs from a particular artist if the iPod does not recognise all of the songs as coming from that artist (which may happen if the particular song features on a compilation album, for example, and so may be listed differently). That's what playlists are for, as iknowyourider has pointed out.

Cheers and good luck
