Populate music library with real metadata

[ungoldman]

I've fooled around with musicmedata and fs-walk a bit but don't have anything concrete yet. @bcomnes let me know if you want to take a crack at this.

I wanted to try to use https://www.npmjs.com/package/folder-walker, but yeah, give it a shot if you want to. https://www.npmjs.com/package/musicmetadata looks good to me.

@bcomnes I might switch gears but I'll claim the task here if I get on a roll. If you get some free time and want to take it just claim it before I do 😉
