Library

Library in the side menu.

Browse artists, albums and tracks. Everything is a canonical record, so an album appears once regardless of how many sources know about it.

Filtering

By format, type, genre, and ownership state. The format filter is the one that gets used — "show me everything that is not FLAC" is a real question with a real answer.
