“Sweet” app is it good? Or a pass?

So I saw this video on YouTube about this app called “Sweet” it’s a music app that every time you play music you collect points to eran gift cards and other stuff. Also daily you get around 8-10 cards that give you points...

Wanted to know if anyone has tried this app? Is it legit? And about how long does it take to at least redeem a 5$ Amazon Gift Card...
