ONM: We Sing Encore Review

It improves on the original in every way, with more songs (40 compared to We Sing's 30), an achievement system which gives a sense of purpose to playing on your own and a 'karaoke' mode which completely removes the vocals and leaves you with just the instrumental.

Obviously it won't be to everyone's taste but if you do like that sort of thing or are in need of a fun slumber party enhancer then you can't go too far wrong.
