Integrate with iTunes Library

Hello, I have noticed the absence of some famous artists, eg. Pink Floyd, Beatles, etc. I gather this is due to licensing issues.

My suggestion is this, because I have these artists in my iTunes Library, why not be able to search for/play music from both Spotify and your iTunes library in Spotify itself, so you can use just one program?

This way you can just download (legally of course) these artists and put them in iTunes, and stream the rest from spotify.

It would also mean that you don't have to stream files you already have, therefore saving bandwidth.
