buy CDs from a traditional record shop then 'back up' to PC;
download tunes mostly from Amazon but other online stores have been used;
on my home PC I use either ITunes or Windows Media Player; work laptop does not get used for anything personal.
I burn new CDs to play in the car – either compilations, own compositions (yeah, I'm in a band: The Wick Effect) or copies of CDs wot I ave downloaded, innit;
download to mp3 player (NOT Ipod – function over form for me thanks) or mobile phone (NOT IPhone) to listen to on the go.
(NB I don't particularly object to Apple products, I just think they're overpriced & overdesigned for what they are)
New(er) car also has an Aux input for MP3 player, but I still like to buy the CD – I like to have the artwork as well as the music
