If a spinner is associated with a clap sound, make it so that there is a looping (duh) applause sound during the spinning without any frequency change? Maybe the volume increases the more it spins?
EDIT: I feel there can be more of these sounds implemented (Luigi mentioned whistled spinners). Finish could be a drumroll that matches the spinner's length (volume increase is proportional). Whistle, which may seem annoying, is like sliders, but it increases volume gradually.
When a spinner is highlighted, checkboxes could appear next to the button for whistle/finish/clap, and you can choose your alternate sound there, so that you can choose between the regular/current sound now, and the alternate sound for spinners.
