Read and interesting article that for some reason I can't link, but it was about the every changing music industry and how tough it is for today's musicians. I won't comment on the entire article, but one interesting fact talked about bands "selling out" to advertisers and how, not to mention it is happening so often that it is no longer an honor and the benefits are smaller, but also the song used to sell a product is forever attached to that product.
My question, what happened to individual identity? Years ago advertisers paid for jingles to support a product and everyone would go around singing the jingle and think of the hamburger, pop, whatever was being sold. Today a car is no longer a Ford, Chevy, etc, it's Vampire Weekend, Muse, etc. and quiet frankly songs used in advertising get old real fast and can make the listener run cold on the musician. If the advertisers like what the musicians are writing why not have them write something specific to the product? It might boost the products image when a song loops in peoples heads and it's directly related to the product. It could also give musicians/song writers another avenue to help support their passion that seems to be more and more difficult to live off of.
