We have been buying CDs still but now we are back in the UK we are going to explore Spotify and see if that would work for us. My husband is a hi-fi geek and he mutters about sound quality and reproduction values, so I think he will need some extra kit before he will be happy listening to streamed music!
I like CDs because I like owning tangible copies of music and film. It doesn't feel right having them on file. What if your computer crashes or something and all of it is lost?!
