This is canon.

Not anymore. Per https://www.cbr.com/star-wars-cantina-music-genre/

The music that is played by cantina band(s) like Figrin D’an and the Modal Nodes is known as jizz, first noted in 1983's novelization of Return of the Jedi. However, the official title didn’t come into fruition until 1995 in the "Tales from the Mos Eisley Cantina." The back cover officiated the music genre: “In a far-off corner of the universe, on the small desert planet of Tatooine, there is a dark, nic-i-tain-filled cantina where you can down your favorite intoxicant while listening to the best jizz riffs in the universe.” Specifically, it’s a mixture of jazz, upbeat, and swinging style that is similar to the music people still listen to today. Music players of jizz are also called jizz-wailers. This musical genre could be heard by the characters from within the story, producing a realistic feel of what is considered entertainment in the Star Wars universe.

Unfortunately, the title is no longer considered canon and is only a part of Star Wars Legends, where anything published before 2014 from within the Star Wars universe is considered not canon. For canon purposes, the first actual appearance of a cantina band was in Jabba’s Palace in Star Wars Episode VI: Return of the Jedi with the band Sy Snootles and the Wailers, also known as the Max Rebo Band. The first song that played over was "Lapti Nek," which played over the death of Oola. However by 1997, a special edition replaced the song with a more upbeat swing on the music. The new song was called "Jedi Rocks," and Sy Snootles' puppet costume was now a CGI rendition of the character. What’s considered canonized and what’s not remains a bit cluttered. But for now, the Max Rebo Band is the only canon jizz music group within Star Wars continuity.
