The Internet doesn't level the playing field for anyone, it just overexposes and over saturates the music, which is why there seems to be more people trying to make music than there are actual music fans. Back when Nelly was hot, you had loads of other big time heavyweights at the same time. In 2013, it's much harder to sustain success since all that music is just one click away, making everything microwaveable. Keep in mind I'm eliminating touring stuff, cause there's a lot of internet sensations out there who tour like crazy from their YouTube following, but are nowhere on the charts nor tv, and are practically invisible.
this is why the pond isn't smaller, there are way more artists out that people DO listen to and it's easier to find new artists and music in general
