Disagree. Been using Spotify for 1,5 years. It is a native app on OSX, feels native and does not use a lot of resources (have you tried this app called iTunes??). They do use flash for ad's though so maybe that is the problem, I pay for the premium account which does not have advertising. For connecting to my speakers through airport express I use the excellent AirFoil app.
