You mean... just any old example of Verse, Chorus, Verse, Chorus, Bridge, Chorus, Chorus?
I'm more of a punk-with-no-solos kind of guy!I was going to post that, but with an instrumental verse after the bridge. Not that I could say what's most common.
[MENTION=15168]famous beagle[/MENTION] is right. Kurt Kobain who criticized popular music ironically chose a pop structure for most of Nirvana's hits. He even said of Teen Spirit he was trying to make the ultimate pop song.
A lot of the more traditional Beatles songs will have some of the more common song structures as well. When I was learning song structure I found listening to their music helpful because there is a good amount of variation on simple song structures. For example "In my Life" has no choruses but instead uses refrains.
