Almost everything I've posted is in my personal collection, but I still have to search Google for Youtube videos of my selections. The audio links I've posted to those few that don't have videos already out there are to my own copies of the songs.
MxPx trivia: The band's name was originally Magnified Plaid, from their flannel shirts. But there's not a lot of room on show posters tacked to telephone poles, so they got in the habit of abbreviating it M.P. on the posters. The guy drawing the posters liked to use little X's in place of dots, so it came out MxPx, and eventually that was just their new name.
