It's definitely more convenient downloading music, especially as you say, when they don't have what you want. But for me the whole experience of looking through stacks of CD's and record albums was something special. Just the same as going into a video game store and looking through all of the software for your system. Being able to download it all directly and virtually just isn't the same. And to me downloaded stuff doesn't feel like you own it, not like having physical packaging and a disc.
