Browser function - Song grouping

How about a function in the browser for grouping songs?

My idea is that each song can be grouped with other songs that blends well together/makes a great mashup or possibly a grouping with the original song, for instance (this list is just a mockup):

Eric Prydz - Call on me
_Steve Winwood - Valerie (original song)
_Javi Mula - Come On (breakdowns blend perfectly)
_Junior Jack - E Samba (great mashup using acapella)
e.t.c...

This would of course require some kind of new popup box inside the browser for grouping the songs together so that each song has it's own "spider web" of grouped songs, so that when I lookup "Call On Me" I get the results described above, but when I lookup Javi Mula - Come On I don't get the other results that "Call On Me" showed (othervise it would become pretty large clusters after a while and the whole purpose would be kind of defeated).

So what do you think?

 

Well, you'll have to feed the spider

 

hehe, yes one would... but in the long run I think it would be worth it..
