I personally make sure all my backing tracks are set with the artist as myself (Brian Gold) and the titles are whatever the song title is. As all my tracks have Brian Gold as the artist (and album and album artist - all three for safety) I can then view in iTunes on my PC all tracks by Brian Gold. Makes organizing much easier.
Be aware though that on a Windows PC the song file can have a filename that is different from the song title. Not always but sometimes. For example, if you download a song file called say "Unforgettable" but then rename it to something you recognize (e.g. Dad's Fav Song) iTunes will still only see "Unforgettable" as the title and will organize it accordingly. Go into iTunes to change it. Or, on a Windows PC navigate to the folder containing your song and right click the song file and select Properties. The filename is shown at the top but if you click the Details tab you will see the song title also. This can be edited/changed to "Dad's Fav Song" or whatever you want and then iTunes (and by implication Stage Traxx) can then organize it.
Good luck
