I'm pretty sure iTunes is just acting a mess. I wasn't able to access the song till right now (last time I checked was like an hour ago). The core Barbz fanbase alone would've gotten this song at least charting.
Well, Billboard does update their charts weekly (every Tuesday) and i dont realy know if itunes update daily but i guess they still didnt update it since the release was being messy because of universal and itunes.
Is it any good? Haven't listened to it yet and have seen only bad things.
dont base ur opinon based on ppl on atrl that are either comparing it to fancy or idk what, it got critical acclaim, ill tell you, it might be considered as a chill/flat/boring song because we're used to having 3 dimensional songs from nicki with crazy voices and lyrics but its a really good song in general like everyone i spoke to about it is loving it. give it a try
