I am a mobile DJ and have noticed an increasing trend for a specific artist or title to be "out of style" only mere weeks after it's "hot." There seems to be no lasting value of music like in the "old days" for the young folks of today. I don't care of you like their music but think of the Rolling Stones still playing their music live and people loving it more than 40 years later. People still request Frank Sinatra at the events I do, even young folks. Even Michael Jackson tunes are still requested despite his current weirdness. Does it make you wonder if Soulja Boy will be listened to with that kind of love 40 years from now? Will people still listen to Brittany Spears, Justin Timberlake, Ludacris, Flo-rida, etc? What music of now do you think will last (more than 4 weeks LOL!) a long time and be listened to many years to come?
