While doing general google search, I found this app
Seems very interesting as it can fetch data from multiple sources
" Auto Tag
Select your favorite platforms to fetch metadata from."
like Spottify, Discogs, Beatsource, MusicBrainz…
Even it can identify your mp3 with Shazam…
It’s a shame I don’t have many mp3’s anymore, but maybe I’ll try fill in some data of my old mp3’s ripped from my own cd’s.
This is very interesting app.
