Lookup Options

Max Results: Many songs are found in more than one album. Set here the maximum number of query results returned for a single file.

Query Delay: At the time of this writing, MusicBrainz imposes a limit of one query per second when querying for tag data, to keep its server from being overly burdened. Each file may take multiple queries to process, depending upon the "Max Results" setting above. If you experience "530 errors" pictured below, try increasing the query delay.

The default delay is 450 milliseconds. On most systems, this delay plus normal processing and connection delays will combine to satisfy the 1-second delay requirement. Note that a 503 error is a generic error that can occur for many other reasons besides a low query delay.

Confirm before lookup: Quiz user for confirmation before connecting online and looking up tags.

Auto-checkbox results: Multiple query results may be returned for a single file being looked up on MusicBrainz. Each result is placed in a new line with its own checkbox, directly beneath the file being queried in the Editor. Check this option to have the first result received from MusicBrainz automatically check-marked. Only checked rows have their data written to tags when the "Write Tags" button is pressed (see Help section "MusicBrainz").

Store PUIDs in tags: Write a PUID returned from MusicDNS into a User Text frame in tags. Supported only in tags that support multiple User Text frames (ID3v2, M4A, and MP4 files).

Use PUIDs in tags: Before querying either MusicDNS or MusicBrainz, look through a file's User Text tag fields for the presence of a PUID already saved during a previous query. Use it, if found, in lieu of re-querying MusicDNS to calculate the same PUID again.
