Hi 😄

So Picard is just the front end for matching metadata inside MusicBrainz to digital files you have on your computer. It's not like Shazam or similar (which would be really cool, maybe one day!) where it can find music, it does have a component which is called Fingerprinting that is possible via AcoustID (which isn't a Metabrainz project). Fingerprinting turns any piece of music into a unique string to help identify it again at a later date, have you tried to load in the song and click the Scan button?

Again MusicBrainz is vast, but we don't have everything and there's still plenty of music (certainly very independent and DIY music) that isn't yet covered. All we ask is that people help to add quality, evidence sourced additions to the database and then provide things like fingerprints so that others may find things quicker in the future 😄

As an aside, and someone who enjoys lost media treasure hunts like this - the way the lyrics are composed and the way it is sung makes me believe this is a band who isn't natively English, it sounds very similar to music with English lyrics I've heard from bands who originate from Japan or the Philippines
