This is incredibly closed-minded. Just throwing that out there.
Legally speaking, there is no uncertain terms about pirating music. It is most certainly wrong, because you're breaking a law. Morally? That's a little different.
I've downloaded countless albums through the site I write for, and they've all been promotional downloads, shared through the community within the site's staff. Only one person reviews it, but 10+ people are getting a free copy. I'm fairly sure any band I've reviewed wouldn't care in the least about me downloading their music for free (legally or otherwise) because I'm giving them free publicity.
When I actually have the money to do so, I buy music. A lot of music. When I don't, I pirate it. I will pirate just about anything I fancy, whether it's new, old, rare, or popular. The word-of-mouth aspect is still there, but the artist isn't getting his 17 cents or whatever from their crappy label. Big deal.
The real crime is how undervalued musicians and artists are by ignoring them, and giving pretty "singers" crap deals for crap albums written by crap writers so labels can shove their crap singles down your throat through crap radio stations who scrape by with crap commercials. CRAP.
I'm sorry, I just feel very strongly about music and how it shouldn't be a business.
