Maybe you already sold your CD's, but you could have considered getting them ripped to lossless FLAC at a cost of about 1.20$/CD. Then you have everything. Sell your CD's, but still have full audio quality backed up to DVDs in the event that you buy a system capable of showing the difference between lossy and lossless file format. Ok, there is the issue of having your music and selling it, but that's a whole different discussion. Check for eg, https://secure.slimdevices.com/order/ripping.cgi
