I'm willing to listen to good music, but I'm also willing to acknowledge when something is a piece of shit. Justin Bieber's work is complete shit on a level where it's constant pandering to a demographic that cares more about the aesthetics of his music (ie: sexy singer + loud bass = fist-pumping awesome). But there are others, like the aforementioned Black Dog, where it's revered as a classic hit because of the melody and since it was a more iconic song from Zepplin other than Kashmir and Immigrant Song.
Personally, I'll listen to anything as long as I can tell the musician/artist actually put work behind it all. You can't just half-ass it and either only put in a catchy progression or some slightly intelligent lyrics. Otherwise, you're just slapping me in the face with your dick while insinuating that you'd be able to write any old piece of garbage, put it on a disk, and sell it to me because I'm that much of a mindless numb-skull to where I'll just listen to whatever I can fuck to.
