These come to mind for treble tests. Specific timing of when in the song, no idea.
Might try:
David Byrne, Grown Backwards (album), Lazy (song)
John Coltrane, Giant Steps (album), Spiral (song)
George Winston, Winter Into Spring (album), January Stars (song)
Lazy is going to push limits and you should hear either harsh or not. I use this song for every new listening equipment, it pushes things a wee bit, through all the frequencies. On Spiral you will notice distinct and subtle differences in the attack on the hi-hat. On January Stars just play from the beginning and see which better compliments the piano treble.
Good luck, happy listening.
