To be fair, I did used to hear it on urban radio sometimes. But I think it was largely because it's Usher. If someone like Nelly Furtado or Fergie had released the song they probably wouldn't have played it much, but Usher was so popular with urban radio listeners.
It was a #1 hit on the R&B charts.
No, it got played because it was an urban song. Polow Da Don is no Dr. Luke, Guetta, RedOne, or Calvin Harris. "Love in this Club" was about as much "dance-pop" as Ciara's "Never Ever." And "Love in this Club" sounds nothing like the dance stuff Usher is doing nowadays.
To be honest, Love in this Club isn't THAT bad, I just kinda hate it because it further paved the way for this dance mess we're in now (although I think Justin Timberlake and Timbaland are mainly to blame).
On a related note, does anybody remember this controversy over Love in this Club being made on Garageband?
Love in this Club was very synth-heavy. It makes me wonder if songs like Party Rock Anthem and Give Me Everything would've been amongst the biggest hits of 2011, if synth songs like Love in this Club, Forever, Disturbia, Womanizer, Hot N Cold, etc. didn't smash in 2008. Or would've synth/electro have got popular regardless?
I wonder what current songs could be pushing new musical trends. I think Adele's success last year certainly is/will.
