On Sunday, when the Windows Phone Dev Podcast aired, co-hosts Ryan & Travis Lowdermilk mentioned they had a few more screen leaked shots of Windows Phone 7.5 aka 'Mango'. However, instead of just releasing them, they wanted to verify and go over them a bit.

Flash forward to today and they've posted new pics depicting two new features which should make folks happy:

Smart DJ -  Found on the ol' Zune HD, it's described as thus "If you have a Zune Pass, you'll hear a mix of music from your collection and from the Zune catalog if you're near a known wireless network. Otherwise, if you don't have a Zune Pass or if you aren't near a known wireless network, the Smart DJ mix will just include songs from your own music collection.". Basically it rivals iTunes Genius and is something us Zune'ers have been wanting for awhile. (For a good 'versus' article, see Gounce's iTunes vs Zune piece).

Disable the camera shutter sound - pretty self explanatory, we can finally disable the ever so loud (and annoying) camera shutter noise. Hooray for spy shots!

Combine with all the other features we've heard so far, Windows Phone 7.5 seems to be going a long way in fixing/augmenting the OS in all the right ways.
