[OC] Correlation between my running pace and songs BPM

I was wondering if there was a correlation between my running pace and the BPM of the songs I listen to.

To get to the bottom of this:

• I downloaded all of my runs from Strava (84 runs)
• Extracted the songs I was listening to at these times from last.fm (483 songs)
• Got their BPM from the Deezer API
• Calculated the per-song per-run pace

And the answer is… no correlation!

I also tried with elevation-adjusted paces, same conclusion.

Note that I don't change songs while running, I start a playlist when I start running and that's it. I was wondering if some specific tracks would "pump me up" – apparently not.
