An awesome (love) song by Metallica which doesn't even have to have the word 'love' in it for anyone to know what it's about.
Another possible meaning is that it’s about a fat kid who tries to get candy from a machine, but the candy machine jams. This is how you get it:
"So close no matter how far..."
(he's so close to the candy yet so far away)
"Never opened myself this way..."
(kid starts crying)
Whore. Sucks ass at singing.
Omfg, you, like, make me wanna la la.
