In no particular order my favorite Ozzy Osbourne songs are
Mr. Crowley
Flying High Again
Breaking All The Rules
I Don't Want To Change The World
Mr. Tinkertrain
Crazy Train
Over The Mountain
I Don't Know
Rock 'N Roll Rebel
Fire In The Sky
Man, there are so many. My list could probably include at least 20, probably 30 songs. Even some of his less popular songs are some of my favorites. Honestly, I don't think another heavy metal band or solo singer has churned out even HALF as many good songs as Ozzy.
