Been a while. I'll return here with something entirely unexpected.
The only punk band I've ever listened to is a band called the Descendents. Excellent ballsy stuff. Mostly ballsy. They had some stuff that was a little more laid back, almost poppy. Also, their songs are usually pretty short. So I'm going to post a handful of them here. I know some people approach punk with some trepidation and I would likely be one of those people, but I think my track record for finding listenable things has proven itself.

The first is "Suburban Home", from the album "Milo Goes to College". This song was featured on the commercials for "Tony Hawk's American Wasteland". It is also featured on my phone whenever somebody calls.

This song, while a little hard-edged, kinda reminds me (the lyrics make this obvious) of being a teenager in the summertime, free of any of life's concerns except for that girl down the street that caught your eye.

This one, "Coolidge", from the album "All", is a pretty groovin' song. Listen for the apology around 1:42 for a laugh. Of note also, is this is one of the very few Descendents songs with a guitar solo.

This one is called "Clean Sheets", from the "Somery" album. A little more on the serious side than the previous songs. Also, another of the few that has a guitar solo.
