Ask HN: Did Apple ban the Lala iPhone app?

Several blogs posted on the new Lala music streaming iPhone app a couple weeks ago such as this one: http://www.techcrunch.com/2009/03/28/an-exclusive-first-look-at-lalas-iphone-app/

However, the app is no longer listed or available in the app directory. Furthermore, there is no promotion of the app on Lala.com.

Did apple pull this app from the directory or is it still "in review"? I'd bet Apple has a close eye on this app as it is clearly a service that is competitive with iTunes. I would not put it past Apple to use their terms of use (ie, "duplicate functionality") in their favor.

Anyone have any info on this?
