One of the reason I went with the Amazon cloud is that I liked that I was playing back my own files. I liked that if I burned something from vinyl and converted to MP3, I could listen to that, not whatever MP3 version they want to give to me. Anyone know if they will convert files through this song match deal if they are slightly different, like vinyl versions and such? If I custom tag some things, will they come through and re-tag things the way they want them to be tagged? Anyone got any ideas how this works?
