Assuming that you could get all the music you wanted/needed from HMV/Amazon/Play etc. Let's say for arguments sake that the big comapnies took on the demand for more obscure artists when all the independents went bust.
I wouldn't care that much. I'm perfectly happy to buy all my music online or from corporate machines.
How would you feel about it? Try to sum up exactly how bothered you'd be, maybe use a rating. 2/10 for me.
