Yes, a few, which I use since I've seen the artist live and since I like the music, so it's likely to get played a lot. For instance there is 'The ghost of Tom Joad', Bruce Springsteen, which has a super-realistic hi-hat crashing in. For low-end performance I use some music from bass-player Stuart Hamm, and for soundstaging I use a recording made by a friend of mine (sound-engineer) from North Sea Jazz festival. For voices I use a recoridng made by me from a barbershop-choir, and so on, and so on.... I think you can listen best with music you play a lot. It's no use buying a system because it's capable of sounding outstanding with classical if you're a Slayer-fan. Then again, a good system should play everything you throw at it.
