Japanese releases always have exclusive bonus tracks. Albums are quite expensive in Japan, so it's an incentive by the Japanese record labels to get Japanese fans to buy the local releases as opposed to imported copies (Where they wouldn't count towards Japanese sales numbers). Sometimes it's something exciting like an exclusive track (Or tracks), other times it's previously unreleased live tracks, and sometimes it's a lot less exciting. Worship Music just had New Noise as a separate track (Since it, theoretically, wouldn't be known to Japanese fans that actually appeared on all versions of the album internationally) and the orchestral remix of Crawl that eventually appeared on Anthems.
Thanks, I know all that lol It doesn't change how I feel. But have an awesome time in Japan! Jealous!
