In the early 10s there was like an explosion of free and legal music to download over the internet, lots of good stuff often impossible to tell apart from big studio productions. Almost daily I downloaded some and then I ran it through mixmeister for an early app aided sorting process while I myself made coffee or something. Anyway, here below are links to the best of them that are still around, for reasons expanded slightly on in the footnote below I think the phenomenon has peaked.

Free psytrance, goatrance, ambient techno and more. Everything on this site is high quality stuff with superb production. Quite niched though, the lion's share of what I find here for running falls into the warm-up category 140-150 BPM.

Kind of like Nerdcore Now (which since has gone dead) but with a mix of original content and parody songs. High quality productions from experienced artists on the front page are free for the first couple of weeks. There's also the Fump SIDESHOW where anyone can submit parody recordings and/or originals.

Technically this is an all genres site but most of the stuff here is comedy music. About two rounds a month they run recording/song contests based on a given title, anything goes beyond that and some of the funniest stuff I've found over the last years came from here.

This blog only lists three free and legal indie songs a week, but with rather lenghty reviews, I've found two songs useful for running here so far so I'll keep it on my list for a while to see what happens.

More Nerdcore Rap albums but from a company who among other ways are releasing some of them thrugh Nerdcore Now mentioned above. This is where I found that Kabuto The Python actually has five albums out and not only the one I first found on NN.

Free and sponsored fully downloadable american hip-hop music of top quality from well known artists as well as debutants. This might be the most surprising and interresting site in the music industry right now. Unfortunately hip-hop's the genre where it's the hardest to find useful beats for running, but if ever Power Metal gets around to this model of sponsorship I'll be as happy as a flying pig in a shitstorm.

Every genre you can think of and then some, every quality you can think of and then some, more quantity than anyone can handle. This is kind of a lottery site with lotsa crap but also the occasional golden nugget, I've made some of my best non-english music finds here.
