I burn a disc of music which I know well and will be listening to at home on the speakers I select. I listen to a wide range of music so my test disc includes rock, jazz, classical, female vocals and so on. It even includes a few tracks which are not well recorded as this can help show you whether the speakers will give a "warts and all" presentation or a "rose tinted" one.
I strongly recommend you do not use music you are not very familiar with, regardless of what your current speakers are like.
