For a complete surround sound system you can spend anywhere from $200 for a complete system to $200,000 for a set of speakers. The price can go as high as your wallet. As for music in surround sound, it's amazing. Yes from and audience perspective stereo is the way to go, but if you want an in the music perspective then surround is the way to go especially for orchestral. Orchestral music is about setting a mood and when you are surrounded by the music you feel eveloshed in it, and it is just an amazing feeling. I also love listening to the Blue Man Group in surround sound.
