looking for some latin songs

hey, ive heard in a club in argentina some songs that i wanna identify,
first one is pretty speedy and goes like

sal-sal-sal... sal-sal-sal... all the time....


the other is some song with acordion in he bacground, and a man singing somehing like "mucho tiempo te espere" or similar....

and the last one i heared in chile, some girl singin:

baila, baila conmigo...
and then i think she says contigo also....

i guess they are all prety popular if there were played in a club... so thanks for the help....!

Here are some possible song titles..
Hope this helps

thanks, im not sure yet about the fuiste sin pensar, it had more live to it...
and the gloria estefan is not the correct one... anyone else might know?
