Take Billy Talent. Anything and everything Billy Talent immediately brings my mind to FFX. Specifically, Mt. Gagazet. Trying to get up that damn hill with that ungodly encounter rate. Sadly, Pendulum's The Island - Pt. 1(Dawn) fell victim to Tokyo Mew Mew. Owl City's Fireflies makes me think of that one guy I really liked who really wasn't interested. The Beatles' Your Mother Should Know is waking up at 5:30 in Grade 11. Gorillaz's On Melancholy Hill is now the dreaded song of treadmills.
It's like any song that you set as an alarm clock, at first it's all "waking up wont be so painful if I'm listening to this!" then you reach the inevitable stage where every time you hear the song you cringe and think it's morning. Lonely Rolling Star from Katamari STILL makes me paranoid that my phone's going off, and I changed that a few years ago. I suppose the only way to avoid this is to either do nothing when listening to music, or only do really cool things. Make sure you're listening to a good song when you do something awesome.
Otherside by The Red Hot Chili Peppers (one of my favourite songs) has always made me think of Dollhouse. I wasn't watching Dollhouse while listening to it, it just really seems to fit. Less the lyrics and more the sound. Because of that, The Other Side by Pendulum (another favourite) makes me think of Dollhouse as well. This isn't a bad connection or anything, I've just always wondered about it. I think all songs named with something about other sides are automatically awesome.
It's like television and movies and everything. I think children must enjoy watching stuff so much more than we do because they don't have the nagging voice in the back of their mind "I KNOW that guy from somewhere! I'm sure of it!" for the whole thing.
