Supernatural: 20 Greatest Music Moments

4. "Turn Into Earth" By The Yardbirds (7.17, "The Born-Again Identity")

"The Born-Again Identity" sees Sam in a hospital, dying as a result of the mental wall broken by Castiel in the Season 6 finale. Dean retrieves an amnesiac Cas and drags him back to the hospital to heal Sam, only to discover that the entrance is guarded by demons. Tagalong Meg reveals to a confused Castiel that he is an angel and that he and Dean had been "bestest friends." Cas looks genuinely apologetic that he can neither remember Dean nor understand why Dean is angry with him, but he agrees to try to get past the demons. As he walks toward the entrance, The Yardbirds' "Turn Into Earth" begins to play. Castiel proceeds to smite every demon, flashing from the present back to scenes from previous seasons (mostly of Dean) with each kill, and he remembers who he is...and what he has done.

3. "Born To Be Wild" By Steppenwolf (7.23, "Survival of the Fittest")

After the failure of Castiel's soul-harvesting plan in Season 6 led to the loosing of the Leviathans, much of Season 7 involved a scrambling by all manner of supernatural creatures to figure out how to send the beasts back to Purgatory. By the end, things are getting a little desperate. In the finale, Team Free Will concocts a last-ditch plan to take out lead Leviathan Dick Roman, the first step of which involves...a distraction. So, for the first time since being sidelined earlier in the year as too conspicuous a vehicle for two fugitives from the law, the Impala makes a triumphant comeback as Meg drives the car through barriers and barricades, blasting "Born To Be Wild" as she wreaks havoc outside of SucroCorp.
