Making the right workout mix is all about tempo. If you're going for a run and you want to bring music that matches your personal pace,
Beatscanner can help. It automatically detects the beats per minute of songs in your music library, and makes playlists of songs at the pace you want. It was originally built in 2007, and the developer just started updating his blog again earlier this year, so the app's design is still a little bit old-school, to put it politely.
If you're not satisfied with the songs you have, there's also a premium version of sorts, called Repacer. Instead of just finding songs that are the right tempo, it changes the pace of your existing songs to match the BPM you're looking for. That way, you don't have to worry about your favorite songs being too fast or too slow to work out to.
