Best algorithm for finding similar songs?
 

There are many sites that have algorithms for giving you recommendations of songs that are similar to a particular song.

Obviously, the recommendations vary in quality. Sometimes the recommendations are spot on, sometimes they are not similar at all.

So my question is simple. Which such system do you think give the most accurate recommendations? Which one do you use?

I don't have/use Spotify. Is there any way to use it's recommendation system for a particular song without being an active user?

(Cool avatar btw)

Well, I was going to mention Spotify as well.
If I got this right, you don't want to purchase a subscription, technon?

I use Spotify for playing albums, but for exploring I prefer YouTube. If I use Spotify for more than an album's worth of songs I get bombarded with adds. So I use it very sparingly so I can get through an album in without interruptions when I do, but then that's it.
