OK, Morphine is really awesome. I mean, not one of my favourites, but still good music. In fact they might be the best "hey this 90s band was good" mentioned so far (I'm to lazy to check all the bands mentioned in this thread).

Interestingly enough: one of the 80s station's tag lines is "Not nearly as mind numbing." It's actually quite true (at east when compared to the 90s station).

For the record I'm sure you could set up a radio station playing music only form the 90s, not kill my brain (very much), and still have a decent selection. In fact I'm sure I'd even enjoy a lot of it. The people at Sirius 9 have terrible taste in music though (and the 90s aren't exactly the best selection of music to begin with anyway).
