Music can be a good motivator when it comes to working out. So Spotify is planning to measure heart rate and motion to help you choose the perfect playlist.

The Guardian reports that Spotify is thinking of using sensors "on the listener's body or in their smartphone to measure their heart rate and then use that to select appropriate music".

Donovan Sung , Spotify's product manager for discovery and recommendations, told the Guardian that using motion, heart rate, and temperature data, Spotify could even start to monitor sleep patterns and mood.

Pairing workouts with music may be an age old practice, but using all sort of data to create a playlist based on that is entirely different.  Let's hope it becomes a reality. [Guardian]
