How popular was Blow by Blow?

[Villavic]

According to Wikipedia, the only single in the Time album was I Do. I was checking this album in the iTunes store. It always shows popularity bars per song, based on a relative measure of how popular a song is compared to other songs on the same release.

I Do got the full bars. But I thought all Christine's songs would get at least some bars, but they didn't. Hollywood got the full bars but NIE and SOL are empty. But what struck me is that Blow by Blow, a Mason song, has all the bars. No Bekka or Bill song has any bars.

I know it is not an official chart but it shows that in this store, BBB definitely had more significative sales than Nights in Estoril and other songs. That surprised me.
