Stuck on TuneGlue

I don't know how I've managed to live without the extremely cool TuneGlue all my life.
It's an interactive "relationship explorer" and with just a few clicks you can see how bands and artists relate to one another musically. Take for example the artist featured in my last post Grandmaster Flash. Enter his name in the search box, click expand and similar artists will appear, click on one of those to see more relationships or on releases to check out their discography.
I'm totally addicted to it, firstly because it is so beautifully designed, second you can point, click and purchase music (from amazon.co.uk, though) and thirdly it totally appeals to the geek in me. I can play six degrees of musical separation to my heart's content. Deeply sad but at the same time deeply satisfying.

P.S. There's another set of relationships in the music player at the bottom of the page....
