MOG is fantastic - I use it every day in the office. Linn has 3 streaming channels of their own music that sounds excellent (jazz, classical and eclectic), but you can't choose what you want to hear, and some of it is a bit weird and not that great. However, if they happen to be playing something you like, the sound is very good.
Streaming music comparisons and quality
At a 320 bit rate, what are recommendations as to which companies are best......I'm thinking MOG.
