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.

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.
