There *is* an easier way. Since the filename titles are only valid on first upload, you simply need a checkbox to "sort numerically" or something like that. That way one won't get collision between track-prepended and non-track prepended songs. Personally, my on-disk format is tNN-TrackTitle.mp3. I would appriciate this feature greatly.

Re your ID3 tags feature, that might become tricky, as what happens when they are included in other playlists? You could say that it's only valid in the primary playlist (don't know how easy that is to find out in their code), but things would get messy quickly.
