Just the next step in changing consumers habits as far as music goes.
I used to collect LP albums (Remember LP albums?)
Then converted whatever was available into CD's. (Remember CD's?)
Then bought some songs on itunes (Remember itun.....wait a little early)
By now I don't need to own any songs and depending on what I want to listen to at a given moment I have plenty of services pandora, grooveshark, you tube etc. Some of these give me European or other continents music that can't be bought in the itunes store due to contractual/legal issues.
Only listening to the ipod app on my iphone when I am in a bad reception area (Hello ATT 3G everywhere please and keep it in 3G) or some news and sports on testicular radio
As an old geezer I think owning stuff like movies or music is so yesterday!
