An interesting recording that has the uncanny ability to sound good through about any audio system:

Recorded and mixed in spanish studios by latin engineers, it is at same time detailed (without being edgy) and warm (without erring into overpowering or loose bass). Those people were definitely doing something right when engineering it, I would be curious if someone with golden ears could "reverse-engineer" what they did and explain what makes the sound so sweet.
Otherwise a nice trip into fado with charming Mariza, and the music will definitely make you tap your foot.
Enjoy!
(and don't use it for auditions of equipment - as I mentioned it sounds good no matter what).
Nap.
