Stream tracking during playlist mixing

Over the past few hours, I've been using the playlist transition mixing tool on Spotify. After I finished, I checked my stats.fm profile to see if streams were counted while I was doing the mixing. I was quite surprised to see that every click I made to listen to the transition I created resulted in a perfectly rounded/exact playtime for each song, mostly of exactly 1:00 min. I'm not sure if tracking this is a bug, but I'm reporting it in case any of the developers think it would be a good idea to create an additional mechanism to better control what gets counted on the profile. Just in case it's helpful to know, I did all of this using the Spotify Desktop app installed on a Linux operating system.
