Anyone know some really catchy dance songs?

yes i do...

Yes. Anything sejak 3OH!3, ular tedung, cobra Starship, Lady GaGa atau Shiny Toy Guns. :D

If anda can find the clean version, Boom Boom Pow sejak the Black Eyed Peas is a fun song with an awesome beat. Jai Ho is good too. Evacuate The Dancefloor sejak 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 Muzik in Me, All I Want, Tell Me Why, and Start Jumpin'.
That's all I can think of right now. :3

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

These are my favorites:

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