If you’re as big of a music buff as we are here, then you’ll be loving this new app for your Android tablet. Qello brings a huge list of HD concerts straight to your device, and the selection is actually pretty legit. Everything from The Doors, to Dr. Dre, and Billy Idol. Installation from the Market is free, and most rentals are about $5, but for that price you get 30 days to watch your shows. Not bad, right?
