Best songs to test speakers

I believe the correct answer is to use whatever music you know and enjoy to test any stereo component. It's of little practical value to use bizarre, unfamiliar tracks for testing, unless that's what you are planning to play at home for your listening pleasure. Take a representative sample of your favorite music and you'll have a good idea of how any component compares to what you already know.

Hint: the best reviewers do exactly the same thing.
