Heard a catchy pop/electro song. Lyrics "Today is a good day for me now"

The song has a male and female singer although it is mainly female dominated. The one line of the song that I can recall went something like

"Today is a good day for me now.." (which was sung by the female lead). Any help would be regarded.

Was it this song?

"Everything Has Changed" by Taylor Swift featuring Ed Sheeran

No not this one, it had a much faster tempo.

This one?

It actually doesn't fit to your description, except parts of the phrase and that there are male and female voices in the song.
It's a french song with just a few english words in chorus, which is sung by the female singer. Also it's mainly a song in Hip Hop style. Anyway i'll give it a try: http://www.youtube.com/watch?v=S43Xi5GrEF4
