I found a track in my collection from college and wanted to include it in my music database. Back when I found it, all tracks on my system were stored with the 8.3 naming structure due to mp3 player limitations. As such, I only have a file name and the actual audio to go on. Shazam (or similar tools) could not ID the track.
