Bot needed for data gathering fom Jalso Music

Jalso Music is a website/app for streaming Gujarati language music for free. It has a database of artists, albums and other types of data. Most of artists in Gujarati language is not covered on MusicBrainz so adding this data would be good. If it does not violate copyrights, I request to create a bot to gather data from the site and upload it on MusicBrainz. I do not have technical knowledge to do it so I am requesting here. They would also benefit from it as they would be able fetch data from MusicBrainz and even connect to Wikipedia for bios.

If the site is suitable for it, it might be better with a userscript for this, similar to the ones that exist for Bandcamp, iTunes, Amazon, etc.:
