Fancy is doing well and is slaying the charts, but considering so many people agree the reasons for its success are the video, the production and Charli's featured chorus, I don't think it's fair that people brag about it's success like it's all come down to how talented Iggy is. Honestly try and tell me that with a dodgy video and an acapella rendition without Charli's chorus the song would still do well.
Black Widow will be exactly the same. It will slay. In fact I think it will go to #1 as well. It's got a phenomenal chorus/hook from a really talented girl with an amazing voice. The production is perfect. The video will be incredible. But just like Fancy, how much of its success can be attributed to Iggy? Barely any imo.
You can brag about the success of her single, but let's be real, she's not the cause for its success.
You should know better than that. Tighten up.
