I saw this pop up earlier today, but Bill over at about.com gets props for sharing the new Janet track “Heartbeat Love”. A similar version of this song called “Not My Love” surfaced about a month ago, but that version was credited to Pitbull with Janet listed as “featured”. It’s pretty cool to hear the evolution of a song through these leaks, although I am sure that wasn’t producer Darkchild’s plan. Anyway, here’s the version that leaked last month. Notice the prominent Pitbull rap:
And then here’s the verison that came out today. Not a ton of difference, but you can hear some shifting around in how things are pieced together, with some elements showing up in different spots.

Pop Music Notes 
it’s only ok
It’s grown on me, but I doubt it will be a hit anywhere.
At first listen, I find nothing impressive here. Why can’t Janet get back on track? Trying too hard?
Ima Die >>Hard Janet Fan,but I dont feel it,this song is NOT my Taste.lol
Janet is NOT able to make Good Music anymore.lol thats why she FLOPS each time=No SUPRISE.lol the good old days with Jimmy and Terry are OVER. So SAD
p.s. this song sounds like a Pitbull track,but NOT like JJ.lol
I agree with all the observations above. ZILCH MELODY. Janet, get back on track and stop trying to make “relevant” music.
It is great song for dance!
FLOP! Poor Janet needs to call Toy Toy for some career advice. She has well and truly lost the plot.
