That was the very first thing I thought of when I first heard Alejandro. I was singing Don't Turn Around with it like a mashup. LOL Ace Of Base only had about three background tracks that they mixed and matched anyway. LOL You can sing most Ace of Base songs over Alejandro.
I LOVE Gaga. My friend dressed as her for Halloween and looked UH mazing. I'll have to ask permission to post the pics on here. She looked FIERCE.
