mmjscrape is a simple cli app for downloading Music Maker JAM songs based on their hash URLs you obtain when sharing via email. It was written for my dad so I could easily download the songs he made and burn them to CDs, but I got tired of keeping it on my hard drive collecting dust.

mmjscrape <path> <...hashes> or mmj <path> <...hashes>. You will find the tracks as m4a files in the path. If one cannot be downloaded, it will be skipped.

const mmjscrape = require('mmjscrape');
mmjscrape('<hash>').then(data => console.log(data)).catch(console.error);

Response object example:

{
	hash: 'a6a7bdd9-98d5-11e7-991a-02fe9cf35e65',
	url: 'https://mmj-live.s3-accelerate.amazonaws.com/assets/music_file/a994dbd9-98d5-11e7-991a-02fe9cf35e65.m4a',
	title: 'Thelonious Junk by bunnyshonis',
	data: Buffer
