Walking at the dark vocals are great and the guitar "solo" too--some ska riffagge, echo and vibrato or whatever. If you know exactly what it is tell me, genres, styles or techniques. Those are peaks in the song.
Some typical, but modern sounding beat. Gay rock screams. Vibraslap is back, the offspring used it on OC Guns. Bananarama abused that instrument on their 1st album in 1983.
Also, the song is very repetitive and it's kinda annoying, but I guess that's how they get shitloads of 4 or 5 stars from allmusic.com.
I'm still somewhat indifferent with them...
