Working with online tango databases 

MusicBrainz

There’s a plugin for MusicBrainz Picard that works with tango.info, which has previously been discussed. Support for tango releases on MusicBrainz is notoriously spotty, since its focus lies mainly on English-language music released by major record labels in the Anglosphere. Hence, relying on MB tag data is not a viable option for mass tagging.

Tango-dj.at

‘El Tango - Pasion y Emoción’ is a good example. The tango.info listing makes a few critical mistakes, so another source is needed. Probably the most complete and accurate information is provided by tango-dj.at.

This script that takes any tango-dj.at URL as input and spits out formatted text that can be pasted into puddletag or MP3Tag:
scrape-tango-dj-at.py

The pattern, which of course can be modified: %title%~%artist%~%album%~%genre%~%year%~%composer%~%lyricist%~%vocal%
Best to use only a single album at a time.

Tango.info

Before writing the plugin for Picard, I had been using a hacked-together snippet of code for scraping tango.info. It is available here: tinfo.py.
