The first three links in this example are good because they have mediafire in the URL, don't be confused by any websites that sound like "mediafirebot/mediafiredownload/mediafireRULES etc." they only have ads.
Similarly, "filestube.com" can give good results if you can't find anything with the above suggestions, but I always reserve it for last.
And if all else fails there's always torrents. I'm on campus so I have to stay away from them cause' the university looks for it, but you might have better luck. My favorite torrent site is demonoid.com.
Good luck, and stay away from limewire/frostwire. They suck.
P.S. if you like folksy music you should download album I linked you to.
