Gaga has already stated she wrote "Just Dance" in January 2007 in an old MTV interview, and it was released April 2008 meaning recorded a few months before. This bitch needs to sit down trying to get some free promo.
Yeh maybe, but I don't think Cascada copied 'Just Dance', it wasn't big in April, and like Natalie said the album was done about a year ago, maybe 3 months after 'Just Dance' was released. They were probably to busy to even take any notice on the song.
They don't sound that much of of the same way, leavin' that aside for a sec, I love both but Cascada was here with Dance/Electro pop before Lady GaGa came out, so, they might sound the same but Cascda were in this genre way before Lady GaGa.
