Google Code-in

Musical works identified on MusicBrainz can be linked to URLs that conform to the whitelist of websites for lyrics.

The objective is to extend the URL cleanup code (written in JavaScript with regular expressions) to match, clean up and validate input URLs to UtaTen, a website about Japanese lyrics. Tests should be extended as well with various examples of valid/invalid input links to this website.

Note: Npm/Node.js is the only system requirement for this task. There is no need to setup the full MusicBrainz server for it. Tests can be run with the command node root/static/scripts/tests/Control/URLCleanup.js directly.
