Your Favourite Track vs You Most Successful

Hi guys,

This topic may have been discussed previously (so excuse me if i'm repeating things) but i'm curious, this is one for the composers among us:

Post a link to both your favourite track in your portfolio and also the track which has performed the best on Pond5.
I'm always very surprised that the pieces in my portfolio which I love the most, often perform poorly where-as those that I'm not as fond of do better commercially. I guess it's down to the tastes of buyers/clients and what they are looking for but I'm fascinated by the debate so thought I would see other's experiences!

I'm a rocker, but my best selling tracks are my relaxing massage music tracks
