To me it's not really a big deal if THP is not featured in this singles collection or if any other songs, like heavy, given up, the catalyst, etc are not in the tracklist. It's not like these songs are suddenly unavailable. If I want to hear THP I know where it is. Also with a limit of 20 songs (18 if we don't count 1 unreleased track and 1 hidden gem that are necessary to better promote a relese like this) there was always going to be hits left out, so one way or another somebody was going to find a reason to complain.
