Thanks for the tip, MG. No message from Amazon.uk, but just accessed the Cloud Player for the first time and saw the 20 MP3 albums I'd bought in recent times increase to 61 as some of my purchased CDs were added while I watched. As there are 754 "songs", I just can't be bothered to scroll through to see if any are new additions, but it's nice to know they are there, just in case some jazz-crazed burglar makes off with my CDs.
Come to think of it, most of those songs - together with a million others - are available for listening for the price of my £9.99 monthly payment to Spotify.
It's all a bit overwhelming when you think how long we had to save up to buy an LP in our youth!
