I… I think the hipsters are right.
You know how some folks go on and on about how things were better when they weren’t yet mainstream? Well, in a sense, they’re right. Just think about it for a moment. When a band is still underground, very little people listen to their music. You’ll barely ever hear it played, and have very little people to talk with about said band as a common interest. Things relating to the band (and sort of also it self) are rare. But once they break through, you’ll hear their tunes whenever you turn on the radio and can’t walk around the corner without bumping into one of their fans. The band has become common.
See where I’m going with this? Rare things are much more valuable than common ones, since they’re way harder to come by. This translates into, for example, hearing a band’s music being a more unique, powerful experience if you don’t hear them everywhere all the time. So if you look at it that way, they really were “better” before they went mainstream. And though I don’t advocate it (still guilty of it though), this does give a nice boost to your “listened to them when they were still underground” and “probably never heard of them” bragging rights.
Somewhat related, there’s also the issue with the way people can (or can’t) handle popularity. That Bieber kid is a good example of letting fame get to your head. Not saying it’s always the case, but popularity can definitely change things for the worse. That all depends on the individual though, keep that in mind.
(I’m not saying popular artists are worthless, drop your pitchforks please.)
