Indie is a word that has a slightly different meaning for every person on the planet. Here is my definition, Indie is simply being oneself, however only people that are "independent" enough from the norm are recognized as Indie. You do not have to like obscure bands to be Indie, you can like a bit of everything and still be Indie, even pop music, Indie isn't even solely defined by what music you like anyway. It's one aspect, but the clothes you wear, the language you use, your personality. Still, only a few people can be Indie, and you can't learn it, your just born with it. Within Indie, people are still not completely independent of each other, take Pendulum for example, alot of people like them, alot of indie people do too. Indie people share interests and do not all like completely different things, here is what I believe the formula for Indie is, 20-15% pop culture, 80-85% personality/personal taste. It's similar to Ribena, pop culture is Ribena, personality is water, without the pop culture(Ribena) , you and Indie(water and Ribena) will taste nothing alike, Even Indie people need some common ground, or being Indie would be boring, and without the water(personality) your just generic old pop culture, you have nothing to offer the Indie community. But then again, that's just how I define Indie.
Normal guy: Hey, sup
Indie: Not much, just listening to some anamanaguchi
Normal guy: That names retarded
Indie: Have a listen (plugs in earphones)
Normal guy: Hey, that's pretty cool and chiptuney
Indie: Yeah, it's good shizz, well, I'll be on my way, see yah.
Normal guy: Wow, he was nice, pretty cool too, he just had some indescribable aura about him.
