Anyone know some really catchy dance songs?

yes i do...

Yes. Anything por 3OH!3, cobra Starship, Lady GaGa o Shiny Toy Guns. :D

If tu can find the clean version, Boom Boom Pow por the Black Eyed Peas is a fun song with an awesome beat. Jai Ho is good too. Evacuate The Dancefloor por Cascada is fun. Cha Cha Slide is a fun classic song that comes with instructions on how to dance to it. C:
Footloose is another classic. There are some fun Jump5 songs that would work for dancing too, like I've Got the música in Me, All I Want, Tell Me Why, and Start Jumpin'.
That's all I can think of right now. :3

Everytime We Touch por Cascada
Heaven por DJ Sammy ft. Yanou
Calabria por Drunken Monkey
Carmelldansen por Carmell (It can get annoying if played too much.)

These are my favorites:

- We Are Golden por Mika (Calvin Harris Remix)
- Good Girls Go Bad por cobra Starship
- Standing In The Way of Control por Gossip
- Dive Into The Pool por Barry Harris
- oscilación Baby oscilación por The DNC
- Clothes Off por Gym Class Heroes
- One más Time por Daft Punk
- Proud por Heather Small (Peter Presta Remix)
- You're Free por Yomanda
