I have not seen the movie yet, but I have listened the song "Dancer" with vocals on YT and i have to say, that I'm glad, that the soundtrack have version without vocals (it have no lyrics btw), because this vocal is just horrible. You can not listen to the song with such a made-vocals. Instrumental is interesting and boldly could serve as accompaniment to a film.
Not only Australia have Friday album releases, but also some other countries like: Australia, Schweiz, Deutschland, New Zealand, Nederland, België, Suomi... + many more. UK and other EU countries have Monday album releases. Albums in the US are always issued on Tuesday.
