It's a hoot.
One of the things I like about it is the ebb and flow, the refinement of the DJs one likes. For instance, say you blip... A Sensational Alex Harvey Band track. You get all the others who have blipped that band, and you add those blippers to your list of DJs.
There's a good chance you'll have the same musical tastes, but you can test that as time goes on. If they keep blipping shite, well, hasta la vista.
However, your fellow Alex Harvey appreciating pal might also blip some great stuff which you would never otherwise have encountered, and then you go in search of that, encounter others who like it, and so on...
