Cashcrops from Music Scenes

First of all i would like to know why i have to press publish post like 8 times for it to properly post... anyway onto my point of this blog posting.
Since Juno came out there have been a few movies (Nick & Norah's Infinite Playlist is a perfect example) that have been pointed directly at people in the Indie rock music scene and this bugs me. Why does this bug me? First of all Juno was good but not Nick & Norah which this blog bashes on. Personally i like the Indie scene and these movies are travesties to them, recently the movie Nick & Norah came to theatres and to be honest i never watched it but one of my close friends who is a die hard Indie chick said that the movie was awful and clearly was just a cashcrop however had great music. I expected an awful movie from the first time i saw the poaster which was Juno's font but a different background.
The point is that studios do this with every big music trend and make it mainstream effectively killing it. (metal is the exception). Modern movie studios have been making movies about music trends forever but recently they've been gradually going downhill, the downhill slide began with Wayne's World 2 which was okay but significantly less funny as the original. Then we where graced by Bill & Ted's Bogus Journey which made me feel dumber for having watched it. This trend wasn't just a 80's metal/ Hard Rock thing it has also occured in hip hop starting with House Party and going downhill to ATL. The problem is when music and culture gets more commercial then you move from great bands like Public Enemy and movies like Boyz N Da Hood to less talented (to censor myself) singers like Ja Rule and films such as stomp the yard.
The secret is to not let big companies like Universal Pictures and Capitol Records get involved and stay with indie companies. Hopefully Indie rock wont become a literal contradiction of its self and will follow this advice. For lack of a better term musicians dont "Keep it real" and end up usurping their culture for money (ex: Kanye West, 50 Cent, and Slipknot). Most likely this will always happen but there has to be a balance for that we can thank Marilyn Mansion, Dimmu Borgir, Spike Lee (eventhough hes preachy as hell), De La Soul and The Rapture.
