TMBG's "Older" track was included by default on some windows installs as part of the media player library circa early 2000s. That's how I found out about them anyway. I'm trying to find more info but seems it was specific to dell machines of the time.
I think in the context of this discussion heavyweight is defined by Section 179 as having a Gross Vehicle Weight Rating greater than 6000 lbs. While the curb weight of a F150 is less, the GVWR is 6,010 to 7,150 lbs.
