I support artists who don't have sticks up their asses about this sort of thing. I've bought tons of albums which were released completely free to listen to online. When I find myself listening to it a few times, I have to say, "you know what, this is great, I'm going to go ahead and pick this up." Good on them.
And often I'll hear random music on youtube that makes me interested enough in the artist to look up more of their stuff and I end up buying it.
Those people have earned my money, not the ones who throw up barriers. There's enough music out there that any barriers to listening to anything specific these days are enough to make people look elsewhere.
Heck, look at this thread. How can we even talk about how great he is without any examples? People resorting to digging on random sites like jukebo.com? Come on.
This is just shameful. Having to reminisce about a great artist by posting Muppet clips.
AND it's blocked in my country (the US).
