I think these guys are interesting for a couple reasons:
1. Their production (music) value is very high and, in fact, I believe they've already started getting producing jobs because of it. They have a nice, fun sound.
2. They also make an effort to put together fun videos. The videos are of home video "plus" quality - not hugely aesthetic, but definitely entertaining.
I think musicians who produce their own music will find this most interesting, but curious what other people think about about them. Here are a couple samples... Sorry that one of them is "Single Ladies" - that song is so totally totally played out... but whatever, it shows some production prowess.
