Thanks for the nice answer man.
The reason I get bummed is because, for example I've been waiting for an album for so long, and I've seen the cd cover and all, and I'm so exited about going to the cd shop and getting it. But then you find out one week before you're going to get it, that its already on the internet. And even worse, you have to decide if you're going to download it, and then buy the album, losing all the fun in buying the album except for the art work. Plus, you might download a version with crappy sound, and then you'll already know the tracks when you buy the album.
I like to listen to the tracks for the first time in good quality.
I probably think about it too much.
I'm interested in modest mouse, arcade fire (its not out here yet), and some others. I use a mac, so I don't know if some programs would work.
