Thank you for explaining the origin of your signature.
I agree the synthesizer riffs are pretty catchy. Better than the rest of the song. 
In my opinion, the "Duh!" before the synthesizer riffs make the experience of listening to that part much better for me. It's also much more satisfying after having to sit through the other parts of the song in anticipation. I did like the bass and drum in the song's ending too though. I only heard of this song because of how overplayed it is in the radio.
Here's another overplayed radio song, although something I think you'll enjoy throughout it's entirety.
