Acts that you knew wouldn't last long

Don't mean to start a negative post but I was curious whether there are any acts and artists that came out that had the hype and backing but you knew they wouldn't last...

I was looking at Ice Spice's career and how she was everywhere and had backing from big magazines and support and being crown the new princess of rap and I thought to myself, really? I just didn't see the longevity of her music.

There have been acts I thought the same but have proven me wrong and came back with a more substantial sound but has there been any other acts that you saw having no longevity?
