I never once said downloading music wasn't a helpful way to not waste money or find new bands. What I did say is that downloading entire albums and saying "oh I'll buy it... eventually..." is outright theft, no matter how you try to rationalize it.
I mean, when you move out on your own, I'd like to see you try that trick on a landlord. "I don't have the money to live here, but I'm going to move in anyway, and I'll pay you rent... eventually.... if I like the place."
Would you like to dig your hole any deeper?
