hey, there are a bunch of very different tabs for metallica's orion (e.g. http://www.tabcrawler.com/ftp/tabs.cgi?browse&bass/m/metallica) and green day's longview (e.g. http://www.mxtabs.net/tabs.php?path=Bass,g,Green+Day,Longview,7369) out there. what do you think are the correct ones? these two songs are currently driving me crazy deciding how to play them.
