Okay, so I've heard all three of these tracks at club Stereo in Montreal and they are all house tracks.
The first one was played by DJ David Morales, and all I remember was something like this:
"Baaaaaaaaaaaby, somethings on my mind and...."
or it mighta went like this:
"Deeeeeejaaaaaaay, somethings on my mind and..."

The second song was like a repeat of a lady singing:
"i'm in love witchu, im in love witchu, im in love witchu"
it had other lyrics too (not much other lyrics), but I dont remember them.

I believe the third song was heard when Danny Torrence was spinning, but I may be wrong. It went like:
"operator, i think i'm falling in love"

If anyone can help ID any of these songs, I would GREEEEEEEEEEEAAAAAAATLY appreciate it.

Thanks in advance
