Universal Music Group has launched its latest iPhone app, in partnership with the UK’s Official Charts Company. The app is called TimeWheel and is a very simple music time machine.

TimeWheel is a database of Top 40 singles and albums since 1955.

The app has also roped in UMG artists like Lady Gaga, Tinchy Stryder, Kelly Rowland, Take That, and Chase & Status to contribute their own lists of favourite songs from the past 55 years.

The app naturally ties into the iTunes Store for users to buy songs (not just Universal artists).
