The problem there is that you're doing substring matches, and we're looking for an exact match.
Say you searched for a title like "away" and an artist like Seether has tracks called "Take Me Away" and "Fade Away"... you'd never reliably get the song you were looking for.
Worse, if an artist like Breaking Benjamin has an actual track called "Away", as well as tracks entitled "Fade Away" and "Blow Me Away", then searching for artist "Breaking Benjamin" and title "Away" with substring matching would not reliably return the track entitled "Away" even though you're requesting it explicitly, by name... you'd get whichever of the above 3 tracks happened to be returned first by MySQL.
Workarounds of varying complexities are of course possible, but I'd rather just avoid substring matching altogether and require a complete song name. Something like
Levenshtein distances was more along the lines of what I was contemplating for the future.
