Right? The designs seem to be meshing together, Rdio is only losing traction (it feels like, at least) to Spotify even though they're greatly improving, and 100B in da bank.
There was a rumor for a while Microsoft was gonna make a play for Rdio. I think Apple's belief is they can do what Rdio is doing themselves -- and with the iCloud streaming and everything now -- we might be getting close to that kind fo thing from iTunes.
I'm now using Rdio for about 99% of my music listening on a daily basis. I only use iTunes to keep track of podcasts, play pre-release albums, and as a media server for TV/Movies on my Apple TV. Besides that, it just kinda sits open most days. The Rdio catalog is just too perfect to add a bunch of shit to my queue - hit play - and forget about it.
