Basic Trope: The devil (and those influenced by him) is extremely talented for Rock music.
Straight: AbbadonRaum, lead singer and guitarist of the Hell's Knights, made a deal with Satan. Now he's the most successful and virtuous Rock musician on Earth, but in order to keep his power, he must convert as any souls to Satan's cause as possible, which turns to be incredibly easy thanks to the almost hypnotic power of his lyrics.
Downplayed: The Hell's Knights are your run-of-the-mill Doom Metal band which overdoses its music and style with Satanist imagery and references; but otherwise, they don't have an authentic connection nor contract with the Lord of the Pit. They aren't even that impressive nor commercially successful.
Parodied: Satan declares himself to be the greatest Rockstar that has ever lived because he can get drunker than anyone, bangs the hottest groupies, spends lots of money into frivolous luxuries, always turns his concerts into great scale riots, gets into media scandals and is an overall galactic scale diva and an insufferable douche! Nevertheless, all true Rock musicians immediately call him for being a frikkin' poser that entirely missed the point: Rock music isn't about acting like an idiot, but about giving a great show!
Zig Zagged: ???
Averted: ???
Enforced: The lead writer of the show is on full Author Tract mode: He genuinely believes that Rock music is a hellish instrument used to convert people to Satan's cause, so he expects that by presenting it into a negative light, he will save the souls of the "confused" youths that enjoy "perverted" music.
Lampshaded: "I might have no sympathy for the Devil... But you gotta admit he knows how to pull a kickass guitar solo!"
Invoked: Satan abducts Jimi Hendrix from Heaven, and forces the legendary guitarist to teach him into the ways of Rock, so that he can use the power of music to gain souls for his cause.
Exploited: After a group of aspiring musicians behold a sample of Satan's incredible rock-powers, the Fallen Angel himself makes them an offer: Unholy talent and success in exchange for their souls and/or the conversion of their audience to their cause.
Defied: The best guitarist on the world challenges the Devil himself to a guitar duel in order to demonstrate that the power of Rock belongs to the righteous... And he manages defeat him, forcing him to quit Rock music forever out of sheer shame.
