I think it is a lot different from what they previously did. That new style could probably be aired on commercial radio. Not that there is anything wrong with it, but it's just to point how different it is.
It's one of those songs that I would enjoy enough to not change the channel when it plays on the radio (or even raise the volume, since most of what plays on the radio is crap), yet I would not buy the album.
It's simple and catchy, makes sense why people would like it.
