Vevo, one of my portfolio accounts, launched their Windows 8 App today. This is one of the best apps, I got an opportunity to work on. This app offers access to 75,000 HD music videos as well as original programming and live concerts from popular artists all over the world.
This app utilizes Search charm to discover your favorite music, and Snap view allows you to do others tasks while watching your music videos. This is just the start, as more functionality gets added. You can download this app from Windows Store.
