Audacity is great. Have it, it does a lot.
Years ago I digitized all my music when we got it from Napster, Limewire, Kazaa, AudioGalaxy and Newsgroups. Newsgroups were the best! Got everything I ever wanted from them but saved them as MP3s, as WAV files were too large IMHO. Was happy with 192 and 320 bitrate MP3 files. Ended up so far with ~ 55 GBs of files, about 10,000 songs/albums on a couple 64GB Flashdrives. So have room on those drives to add even more files as needed. Take a thumb-drive and plug it in my vehicle and have endless music and never have to listen to any commercials on the radio anymore! It's great!
