# Web Services

This page describes the web services available in Tagger

## Download MusicBrainz Metadata

Identifies a music file through MusicBrainz and downloads its metadata to use in Tagger.

This service utilizes the AcoustId fingerprint of the file (generated with fpcalc) to determine MusicBrainz recording and release IDs. If IDs are found, metadata such as title, artist, album, and art will be downloaded and set in Tagger.

Finding metadata through MusicBrainz isn't 100% reliable and may not be available for uncommon songs.

## Download Lyrics

Uses the tag's title and artist information to search for lyrics of the song.

This service utilizes NetEase's Music163 service for obtaining synchronized lyrics.

If no synchronized lyrics are found/available, Tagger will use Letras for obtaining unsynchronized lyrics.

Finding lyrics through these services isn't 100% reliable and may not be available for uncommon songs.

## Submit to AcoustId

Submits data about a music file (identified via its fingerprint) to AcoustId's database. There are two things that can be submitted about a music file:

- ### MusicBrainz Recording ID

  A user can submit a MusicBrainz Recording ID to submit to AcoustId. This will pull all data from the associated recording id and use that for sending metadata to AcoustId.

- ### User Metadata

  A user can submit their metadata from Tagger to AcoustId.

A proper AcoustId User API Key must be set in Preferences for this service to work.
