Get the gold CD of "Bob and Ray Throw a Stereo Spectacular". It's fun and an excellent system tester. I don't expect most of you 'philes to be old enough to remember Bob and Ray so just trust me. If I recall correctly the CD is on DCC, which is one of the reasons why it sounds so good.
Music to make you laugh by
No, I don't mean the text of a song as an example. Rather the musical content of a given piece of music, which by listening to it, be it in concert or at home in front of your rig, has made you laugh out loud or grin or smile, because it was funny or amusing in a clever way.
