i really feel that WUTB has the best hit-potential as a single, esp now that many in the GP consider Adele as "only having slow, sad ballads" which is very far from true, but the GP kinda think so.
perfect, catchy midtempo, powerful and def a more qualitysong that has more "Adele-stamp" on it than SML.
and i notice that generally WWWY is not doing anything yet outside NA (where it's getting really strong esp US), except for scandinavia but that's because her p/f of it on Skavlan were shown on their new years special. maybe it's just not played at all on radio so ppl dont really know about it? tje ones who does already has the album
AIA is obviously doing amazing, but i still don't think it's good single-choice now, another piano-love ballad, and it's below her standard..but at the same time, the GP seems to love it so i dunno...
