Have been following this via Twitter - or trying to - don't have your insight.    
I'm still skeptical this will be a good thing for anyone but Google . . right now Lala looks like the biggest beneficiary.   Am fine with that - found them because of some sites that use their player and like what they do . . Rhapsody is still my go-to for "leased" music though. 
This move seems to be bleeding into all the music news / speculations . .  saw a piece earlier today re: Ticketmaster making a mistake in not snapping up Lala.  

Personal use perspective . . 
I have been finding the obvious things on my own since shortly after started playing online . . what I want from a search is the less visible content driven sites like TIS. 

I've been using Yahoo search as a first choice for quite awhile because usually got more of what I was looking for on 1st / 2nd page  - - dream scenario for me would be that they decide to become the go-to place for the less casual hunters.
