MadonnaTribe sources can bring more exclusive news about two tracks of Madonna's new album.
Of the lot of songs produced by Timbaland and Justin Timbelake that MTribe reported about shortly after they had their final mixing in Hit Studios Miami in November, "4 Minutes To Save The World" is possibly the one with a stronger "classic" Timbaland vibe.
If there's actually some "hip hop" or "urban" vibe in Madonna's new album, we've been told that "4 Minutes" is probably the track where you can feel it the most. The song has an instantly catchy vibe, with percussion layers and hypnotic synthetized strings. While in other songs of the album Justin can be heard on backing vocals, as previously reported "4 Minutes To Save The World" is actually a duet as in this song's verse Madonna and Justin basically sing one line each or better answer one to another on a back and forth basis.

On the other hand, we've been told that "Dance Tonight" sounds like the funkiest song of the lot. You could say it's a dance track from the beginning to the end - dance in the title. dance in the theme, dance in the lyrics, and dance in the instrumentation.
It has a captivating late 70's - early 80's disco sound - fingered bass, claps, triangle - recalling songs that made the history of dance as we know it and groups like Kool & The Gang, Skyy, Delegation, even a bit of the early Michael Jackson and huge references to the signature sound of Narada Michael Walden and to the origins of disco-rappping.
To compare it to another Madonna songs the most similar thing that comes to mind are "Don't Stop" or maybe "Your Honesty" from the Bedtime Stories sessions.

Lyrics-wise "Dance Tonight" also shares the same idea of fun of Don't Stop reprising the classic Madonna theme of letting yourself go and be guided by music, and doing positive things while you dance the night away.
