Sony has relaunched the SingStar website with all sorts of new features that let you browse the series' back catalogue of songs and view performances from other players.
The new website's catalogue section lets you rifle through over 1500 songs that are available to SingStar fans through the numerous disc versions and on the SingStore. You can also preview them and see the best performances from other players.
Those performances are ones you can upload from within the game, either as videos or still shots, and if you're not bothered about the songs you can just browse those until you're merry in the face.
If you're particularly bored (nice work if you can find it at 9am on a Thursday), there's a shuffle function to preview random songs from the far reaches of the game's enormous catalogue.
