I'm not sure why the recording industry can't release a copy just for the public, free of charge with stereo quality. The DVD's would cost $50 or so but then you get a master copy with 12 separate tracks (or whatever) so you can choose to listen to just one source instead of the whole group as one track (free edition)
Studio video could be included, out-takes, ect. If they need more room then set up a web site that only allows entrance through the DVD to just info for that one DVD (membership lets you cruise around a tiny bit, the DVD has a lot more detail available.
Since hardly anybody listens to a radio anymore bringing a free version lets more people hear the song, have the band's name a part of the song (start or end).
My music taste's are quite small but teens are quite prone to the temptation, a free version would be passed around like wildfire compared to the underground that is used today, the wider the music is heard the more will shell out for the higher quality version. Some would be quite happy with an AM version of the same song/.
All music should fall into public domain at some point in their life. An albulm 20 years old has made just about as much as it ever will, give it away. The suppliers website would get lots of hits just by people seeing whats been added to the public library.
Say I have a very expensive piece of software, what would be out there to stop me from starting a company that has lots of really expensive (specific) programs and I set up icons on my website that would start the program running in user mode. The person gets to do what they wanted and the odds are most would need it very intermittenly rather than very often. Charge a (small) fee to gain access and it's legal is it not?
