It's certainly Interesting.
The second thing I noticed was the interesting mix of reggae and hiphop. I wish they'd pushed it more towards the reggae side, the hiphop is cool and all, but they've done it before and it feels more like they've just mashed the genres together rather than giving one an interesting twist. Bom and Minzy's voices are fantastically well suited to reggae, & I would LOVE to see a duet track from them in the genre! CL's rap is definitely linking back to the Baddest Female, which I can understand, but still, it's unnecessary. She hasn't been gone long enough to warrant such a strong link to an 'old' promotion and it almost felt like Falling in Love was just a continuation of her solo promo and the other girls just happened to be there. What prevented that is her complete lack of singing lines. The throw to Fire was good, that is an old promotion that really is fun to pull back up, the Baddest Female doesn't have that nostalgia yet. The song itself is pretty good, the verses are actually pretty fabulous, but the rap breaks are a bit too much. Dara's raps are actually better than CL's because they suit the atmosphere of the song whereas CL are definite breaks. Also, the bass is WAY too heavy, it muddles the higher lines because of harmonic interference. It suits CL's raps, but that's it and those should be tossed or changed anyway.
My one other problem with it is that the choreography feels completely unrelated to the the track. I like the touch me sections, those make sense, and Minzy's second verse (around 1:50-ish) almost does too (and CL's 2nd separate rap), but for the most part it felt like I was watching an MV on mute with itunes running a different song. It just doesn't mesh well at all.
I still like the song and the concept and we've been promised more 2NE1 tracks in the near future, so I'm hopeful.
