If you own an I-Pod touch or an I-Pad, there is an app available from the "App store" called Music trainer". It will allow you to instantly "import/download" any tune you have in your I-tunes library into this app. You can then slow it down, change pitch, etc. I like it because i can pull up the app on a whim, like when I'm thinking of a tune and import it on the spot. I have never used other "slow downer" programs so don't know how this compares, but it works just fine for me and my wife. -- Steven
