This was going to be my tip.in a way beaten to the post by
little plum

)) think my version is a better option
what I use myself is
winamp there is download patch called (
pacemaker) which allows you set tempo, pitch, and speed, to any music ripped to your music folder ie "take the lead" to settings you are happy with I think it is a lot more flexible :welldone
also another program used by myself to get me back to reading music after a break of nearly 50 years is
note trainer.gets you back into reading very easy.:welldone
hope these tips are of use to someone
