Catchy songs that get stuck in your head

[CHE.R.RY]

All of these songs are catchy and get stuck in my head:

Hollaback Girl (Gwen Stefani)
Wind it Up (Gwen Stefani)
Sweet Escape (Gwen Stefani)
Promiscuous Girl (Nelly Furtado)
Say it Right (Nelly Furtado)
Don't Stop the Music (or w/e it's called by Rihanna)
Viva la Vida (Coldplay)
Rehab (Amy Winehouse)

And that's all I can think of at the moment .
