my own opinion
as a downloader, I would not have bought more than half the music I have done if it wasn't for the ability to download and listen to an entire album in the comfort of my own home, i never did like visiting HMV and standing around listening to pop crap on public headphones while other people stand around tutting.
plus, I have no plans to change my current buying routine ... listen, like ... buy CD ... not downloads, never downloads, always the CD or DVD.
as for the future, i think it would make sense for most artists to release online as downloads and through stores to ship CD's and other merchandise.
oh wait, that is happening already ... so, the recording industry is embracing the technology available already.
the same goes for movies ... if i like it, i'll buy the DVD ... i don't go to the cinema any more or less than I ever have (except maybe in my teens when i obviously had more time).
I can't be alone in doing that ... surely ?
I do believe in supporting the artists which is why I do buy what I like ... although i am questioning why I bothered to buy 30 seconds from mars' last 2 albums
