Normally your media player will supply the relevant information for the tags using an internet database.
But sometimes it fails you. There are a couple of alternatives.


MP3Tag is a powerful piece of freeware.
Beside FreeDB it can use, MusicBrainz and Discogs for tagging.

Cover art

A Google image search often retrieves missing cover art.



A lot of information about composers and performers often including a discography can be found here.

All Music Guide

A well-structured source of information.
Good source for classical music.

If you look up Beethoven you get over 700 entries including all WoO (Werke ohne Opuszahl).


IMSLP (International Music Score Library Project)

Lots of information about composers (7000) and their works (55.000) in the Petrucci Music Library.

You can even search by melody!
