great, but stingy!

great app, great fun, but the seven songs included in the "starting version" are not the "greatest hits": "mamma mia," for example has to be bought separately. the same for "waterloo" and "fernando." anyway, the idea is sheer fun and I recommend it, if you want to sing along with the best disco music from the 70s.
