I shall not go into the music of Sia herein. This is already a matter of taste. However, I must warn the MP3 download. The audio quality is sometimes so bad that I thought for some time that my headphones were broken. But it turned out that there simple (but solid) is clipping, which is either happened already masters of the recording (hard to believe, then the engineer would include fired), but more likely during processing as MP3 recordings made unusable. The problem is not heard at all points and not to the same extent, but particularly "Chandelier" is completely useless.
