If you still hate This Is How We Do after hearing this, you're a liar.
Well, it stops her sounding bored and disinterested I suppose, but inhaling helium doesn't sound much better...
Besides, the main thing wrong with the song is the lyrics. Sounds like a day that I'd regret agreeing to join my "friends" (not sure what I had in common with them) on. Too much a teenage girls day out, not enough things I'd enjoy.
The original instrumental is by far the best part of This Is How We Do anyway, so...
