Song tag/album/artist manager?

Is there any equivalent to the “Creative MediaSource 5 Organizer” for the Sansa Clip+? I tired Songbird, but it doesn’t seem to load up the songs that are actually ON the player, only tells me how much space I have left.

I want to be able to retag files that are already stored on the device.

MP3Tag will do it.

No it won’t, can’t mount the player.

?  Really?

You dont mount the player you treat the player like a flash drive when you set up the Library in Mp3Tag you just find your music. Its not based on your player its based on the folder structure.
