David Cronenberg directed a film called Crash about people who get off on vehicular accidents. Paul Haggis, eight years later, directed a film with the same title, about racism (or a racist film about racism, if you ask a cynical white person), in 2004.
Certainly, Haggis wasn't trying to fool viewers, in The Asylum tradition, into thinking that his film was related to Cronenberg's critically acclaimed-yet-little-seen movie, but he at least must have known that a film with the same title existed. And he didn't give a shit.
Neither did Jay-Z and Kanye West, I imagine, give a second thought when they pilfered the title "Welcome to the Jungle" from Guns N' Roses.
I care, though. Tonight, after typing "good vibrations" on YouTube's (shitty, advertising-driven) search, the first page of results were a pagan mix of the Beach Boys's classic song and Marky Mark and the Funky Bunch's early 90's hit.
So, a song fight. In one corner, Brian Wilson and company; in the other, Mark Wahlberg and his bunches funky.
The stake? Song title ownership. Forever.
