How it knows what was playing on mile 9.
How songs meet miles
Spotify history provides listening times; Last.fm provides song starts, with listening duration estimated from track metadata. Strava logs where you were, second by second. Line them up and every stretch of a run gets the song that was on, along with your pace and heart rate.
Where the music comes from
Connect Spotify directly, or through Last.fm, to add songs to new runs. For runs before that, and for podcasts, ask Spotify for your extended streaming history and drop the file in. No Spotify? You still get your runs, photos and routes.
What counts as a listen
A song counts if you heard a minute of it, or 40% of it, or picked it yourself. Anything shorter is a skip. Skips still color the route, but they never make anyone’s favorites.
What the lines mean
The line under each run comes from that run’s own data: a song on repeat, a switch from podcast to music, a stretch where you picked up the pace. It only says what the data shows.
What it can’t see
Spotify syncs directly or through Last.fm. Last.fm can also provide music recorded from other players, but setup guidance currently focuses on Spotify. Listening that was never recorded can’t be recovered, and podcasts arrive through Spotify history files.
