What do you use MusicBrainz for?

[jesus2099]

Managing my physical collection.

And find new interesting music through my known artist loved music relationships to music or artists I want to discover.

And avoid buying duplicates:

The main reason I use MusicBrainz is to keep track of my collection.

When I am in a flea market, second hand shop, CD shop, I want to know if that compilation or single will bring me recordings I don’t already own in this artist albums or if I already have any edition of that album, etc.
