Probably very easy...
First track...
A very old sounding Italian piano track......
At the beginning there's a male vocal 'party people, let me see if u can dance', followed by some great melodies, then about halfway through a female vocal kicks in, with what sounds like...
'On the floor tonight' (which just sounds a bit daft, because it's probably different).
2. Probably an old belgian track, might be called Orgasm, I'm sure it's got a sample 'Create a cosmic orgasm', voice sounds a little similar to Fantasia- Inner light.
3.It might be by Ecstacy Express by The End.
'Are you ready for the music'.......vocal
Cheers in advance
