I prefer MusicBrainz and fallback to mp3tagger for obscure releases. MusicBrainz can Identify a track with sonic lookup but I find the best way when a rip does not have the artist and album tagged is to hit the lookup in web button. That opens musicbrainz on the web, type in the artist, click the album, click the green tagger icon. That inserts the album into the musicbrainz program. Then you can just drag the untitled track on the left window to the correct track in the right window and hit save. Set it up right and it will rename the track/album and move it to your music library in the artist folder and album folder with the album art imbedded and as a standalone Poster.jpg file, also, any PDF booklet that might come with a digital release. You only need to set it up once. After that, tagging an album takes seconds.
My Nvidia Shield with Kodi + plexkodiconnect = Crazy easy file management. Use Plex to keep things organized and Kodi's audio engine + Nvidia's DAC for playback and GUI. It's the most beautiful listening experience.
I keep my multi-channel mixes separate from stereo. Plex helps with that. Otherwise, Kodi will just mix them all together. Plex will also allow you to listen remotely in lossless or lossy.
Take a day and make this happen and you will regret everyday you wasted not getting setup earlier.
Good luck. You will lose some hair...
