Get your head straightened, classic rock is a great way to appeal to everyone. Parents know Led Zeppelin = they find the trailer amusing. Parents find trailer amusing = more incentive to buy it for prodigal being. Prodigal being asks for Taken King = profit. Now I like LZ and all, but there's a lot of songs that fit that trailer as well, for instance... AC/DC, The Offspring, Metallica, Dragonforce, Def Leppard, Kenny Loggins, or even Queen. If you're not into classic rock... Dubstep, Techno, electronica, dance, polka, folk-song, classical, Lindsey Stirling, and many more. The trailer was fine and the music accompanied by it was great! I seriously watch that ad on YouTube whenever it comes on, I don't skip it because I like to watch it.
