Any specific type of music genre's name for (eg.) Gwen Stefani's "hollaback girl" or Fergie's "London Bridge"?

I'm trying to choreograph a certain little dance routine, and I'm
looking for more songs with similar beats (like Gwen Stefani's
"Hollaback Girl"  Fergie's "London Bridge") , does anyone know if
there's a certain name for this type of music?

if not, then are there any recommendations for similar songs? I'm fine
with any-languaged (lol) songs :)

thanks in advance!
