What is kid cudis song day&night about???
Songs can sometimes just be really random and not have specific meaning. You can interpret it how you wish. This song has such a great beat, I love how choppy it is, I don't care so much what it is about, but I'd say its about a guy who wasted/is wasting his life by being such a stoner.
Being a stoner basically. Getting high.
a breakup I think
