Well not quite, because you either paraphrased poorly or missed the point.
I said that songs with official MV's, like the recent IVE one, aren't 'b-sides'. They are singles, in this case a pre-release single.
It still doesn't invalidate my claim here that a pre-release single is hyping up the main event. It's literally the job - to serve as promotion for the group and for their upcoming album drop. In fact you could even argue that is partially even the purpose of main title songs - people like the song, think it's good, buy the album or invest in the group - that's how the group makes their money.
So yeah. It's a single, a pre-release single, and it's part of the promotional period leading up to the main album release and main title track, so people going on about 'no promo' are quite frankly - dense.
