Cover art for The Hill lyrics by Bombay Bicycle Club

It does feel like lost youth; or trying to recapture something that cannot be found again. Quite mourning and a little sad although you dont get that feeling The repetition may signify the regret 'I'm trying but we're all falling out,' may signify old friends growing up and friendships failing

All the same, it's a fantastic song :)
