Oh, one other thing...

If you already have the MP3s tagged properly on the PC, you can drag them up to the top of the tree rather than into a playlist folder. You can also drag them onto the main Emplode "home page" (the white screen with the web links on it). This will make them automatically go into the artist/album trees without going into playlists.

Note that in Emplode, deliberately dragging a file onto an Artist name will re-tag that file as that artist. I think the same goes for the other categories (i.e., drag a Rap song into the Country genre will re-tag the genre field for those songs).
