I think it was some sort of anniversary, but I dunno. Imo, it was their 2nd strongest, right behind "the Hot and Heavy". I mean their would be no Hot and Heavy though if it weren't for In Vogue cause they would have had nothing to fall back on after the crappiest album they put out was released "Worse than a Fairy Tale". They knew they couldn't make that again, even they thought it was awful, so they took it back to their roots, which was In Vogue.
i loved the experimental vibe WTAFT had, but i guess not everyone was expecting that right after 'in vogue'. i feel like the 'hot and heavy' combined the best aspects of both.
