I don't remember now. It's been about a year since I did it. I got tired of tracks mysteriously disappearing out of my library or certain versions of a song not being available (licensing issues I assume) ... so now the RIAA gets none of my money instead of some of my money, because they want to be greedy.

I would imagine any of the paid services would work for the most part but I can't say for sure, I'm sorry. The one i used just downloaded everything at once (about 1500 tracks worth I think)
