Is there an app that allows you to take any song and customize the beats per minute?

When I saw your question, I realized what I nice thing that would be for myself when I want to customize some music for my teaching purposes.

A quick google search showed more results than I expected, and the apps are so cheap that you can hardly go wrong picking one of them.

Thanks for the question. I did not realize that I had that problem until you mentioned it 🙂

I use an app called Tempo Magic and it’s fabulous … it lets you speed up or slow down the BPM (Beats Per Minute) of any song, straight from your iPod library.

I use Tempo Magic. It’s a free app I found through IDEA Fitness Journal.
