Songs that have great imaging in stereo.
I mentioned this song before 'Give Me a Sign' by Jean Michel Jarre, Metamorphoses. What you should hear is a 3D like ghostly voice in the background that seems to float above the music, more apparent the better the system. There's a few other songs on the album that have this kind of imaging.
Another is the train in 'Magnetic Fields'. You should hear the train move from right to left giving the impression it's moving.
Another is the drum solo in In-a-godda-da-vida by Iron Butterfy. You should hear the drums move from right to left.
One more, 'Comfortably Numb' by Pink Floyd, Pulse. If you have seen the video, when he's kinda twisting the guitar on the solo, it should sound like a siren. I usually turn it up loud to excite the room to hear this cool effect.
