I often find that artists who I like tend to work together (this is especially true in hip-hop and electronica, but also in rock music as well through side projects). I&#x27;ve found some of my favorite albums this way; and it&#x27;s weird esoteric stuff that other people tend to like (just harder to find unless you know to look for it).<p>Is there an algorithm that suggests music based on the degrees of connectedness to the individuals who made the music? I discovered Kanye West long, long before he made it big because he did a guest track on a label-produced mixtape. I said &quot;man this shit is dope&quot; and tried to track him down, but was only able to find other guest tracks on like a Mos Def album and a Common album (this was in like 1998, 5 years before he released a solo album).<p>I really miss that way of finding music, because it introduced me to a lot of artists who were similar enough I would like them, but different enough that genres started to morph into one another. A good example there would be Nine Inch Nails vs. How To Destroy Angels - Trent Reznor is behind both of them, but HTDA has a much more haunting, ambient sound compared to the sharp edges and distorted beats of NIN.
