(and i hope later you can share whatever that was with us
there was a guy on the Colbert report a few months back talking about this archive online, and i wish i could remember the name or i'd post the site. but this guy had gone all over the world with a two reel recorder (and later cassette) in the 60's, 70's and 80's collecting tribal music, nursery rhymes, childrens songs, folk stories and music. wanting to share with the world what these people in far away lands had to offer. some didn't want to be recorded, but many did. They didn't want fame, but wanted people to hear it.
Now, people have an outlet for that. and alot of the good stuff are hidden treasures. for example as i said alot of fan stuff for mlp gets made every day, so in the 2 years since the show started fans have made literally over 3000 pieces of music (most of that in the last year actually). spanning every genre.
its easy enough to find top 10 or even top 100 lists, but usually those are just whats popular, or got found because the artist has alot of subscribers. there is an archive though that has collected every track they could find and put it in one large bittorrent file with updates coming once a month to add new tracks. sifting through it i find so many really great pieces but when you go to their youtube page the song may only have maybe a few hundred views, a few have less than that. When the songs in those top lists have a few hundred thousand or even a few million views. but they are still great.
A few artists offer the option to donate, or have a bandcamp account where the price for each song is often "name your price", but usually its only so they can get better hardware or software. but most of the time the only time money has ever changed hands for the music is from the various charity albums that have been done. the vast majority just do it for fun.
