Ozzy Osbourne left behind a very heavy legacy. Here's a look at his best songs, from Black Sabbath's "Paranoid" to "Crazy Train" and "Mr. Crowley."

Black Sabbath guitarist Tony Iommi said he thinks bandmate Ozzy Osbourne was "determined" to play the group's farewell show and "really just held out" to do so weeks before his death.

Osbourne died on Tuesday at 76, just weeks after he and Black Sabbath performed at their farewell Back to the Beginning concert earlier in July.
