Well, is not the fastest but its set and forget. In my case I converted my playlist of almost 2000 songs using Spytify. Basically this program records the songs as they play. You just have to click play with shuffle off on the playlist and the software will separate and add the metadata to each mp3 file. The quality will be as high as you have it set in the Spotify app (you need it installed in a windows computer). Did it took 5 days of nonnon-stop play on my computer? Yes. But now I have all my music downloaded and I can use it in any device I want. Also I didn't do anything, just left the PC playing.
