Hey
The only thing in this song is a catchy bassline and a female voice that sings: "naa naa naa naa...(pause) naa naa naa naa naa , and during the last couple of 'na`s', a female voice(probably the same one) sings: 'woo hee(<-high pitched), we`ve got to sing a song' or something that is really close to it.
The first 2 'naa`s' are in a certain tone height, and the 2 naa`s after that have another, lower tone height or pitch.
I guess the genre is house or dance house.
The song also has a really catchy bassline.. in the style of mojo-lady.
Probably already from post year 2000 although it could be early 2000`s.
I used to hear this song on the radio when I was younger.
I live in Belgium.
Thanks in advance!
