@ rocco_thestreet $P headwinds soon? $AMZN $AAPL chasing music services, how will they come out on top?— Alex Colcernian (@ALxSee) April 14, 2013And, yes, it dominates Internet radio today. It doesn't merely have a lead. It dominates. It hasn't mattered much who has entered the space. And we'll end up saying the same about most, if not all, future competition. Even Apple ( AAPL). Sure, Pandora's stock might crash on new Internet radio entrants. It already has, several times, on the Apple rumor. But this noise does nothing to prevent what have been incredibly predictable share price rebounds or derail the long-term narrative. You know where I stand, but, often it makes sense to bring in another voice. I don't dig many Wall Street analysts, but Richard Tullo of Albert Fried knows the score on Pandora.
