I'm never going to buy another physical cd again. Not after I have found MP3va. It contains a lot of artists within a variety of genres, its really cheap and the user interface is nice and non-tecnical.
I was happily surprised when I recieved a small present from mp3va on my birthday. Only 3 dollars, but still it corresponds to two albums, and the thought also counts.

The only critique so far is, that they didn't accept visa last time I tried to add money to my account. But "with a little help from" support it was fixed with PayPal.
