Even though "Teen Idle" isn't among my favorites from "Electra Heart", it's pleasing to see it in the top 10. Deserves the accolade of the highest placing album track, too (although many other songs deserved it more).
I wish it didn't get so uplifting in the melody (except for that 'super, super, super suicidal' part, which is juxtaposition at its finest). For example, "Valley of the Dolls", while not having the darkest production possible ("Electra Heart" doesn't really have any pitch-black moments when it comes to production), has that sad melody that fits the lyrics and the atmosphere perfectly and that's the only thing that "Teen Idle" misses to me completely amazing. The song grew on me, actually, and I would've given it a 9 now.
I remember stumbling across that video of her singing the song to the kids and it was a hilarious, amazing and WTF moment at the same time. Only Marina could do that and that's why I love her. The moment that cracks me up the most is how right after she sings 'a 21st century whore' it cuts to the children clapping. Priceless.
