Songs you use to determine if a system sounds good

One I have on cd is Tchaikovsky waltz from swan lake. Which is also a good indicator of preformace with a single track.

Do you guys really use Youtube to test your sound system? Surely the quality of the recording is more important than the music? .

Definitely yes, if we talk about the mastering. A badly mastered recording in hires sounds worse than a lossy compressed good mastered recording. The music is a question of individual preference.
