Quu app for iPhone and iPad

"If you’re looking for an app that is focused around queuing up music, Quu could be the one for you." - AppAdvice

Quu is a minimal, yet powerful music player bringing you "iTunes Up Next"-like feature to iOS.

Quu allows you to queue songs that you would like to play next to minimize the idle time between choosing songs and allows you to focus on what you are doing rather than finding a good beat to go along your task. Great for the gym, road trips, studying, or just general use.

Quu is also integrated with Last.fm, log in with a Last.fm account and scobble your tracks and view your top played tracks for the week from all of your devices.
Quu also connects you closer to your favorite artists by giving you ON TOUR notifications and more information about your artist including fresh pictures that are updated frequently.

Quu also allows you to quickly adjust volume by holding anywhere on the screen and then moving finger up or down to adjust volume to be higher or lower. We prefer louder :)
