Lyric discussion by The_Mysterious_Dr_X 

2D says "I ain't happy, I'm feeling glad. I got sunshine in a bag. I'm useless, but not for long. The future is comin' on" because he's Stuart "2D" Tusspot and he's always on a combined sugar and aspirin high.

If you know anything about the characters, you know that the rapper in the song is a ghost (named Del) who lives inside Russel's head. The entire rap is all about Del's mammoth-sized ego, how he can alter reality as a ghost, and about the impossible existance of Gorillaz in general as they're cartoons.

"You think it's fictional? Mystical?" - Referring to the fact that the Gorillaz really aren't real and people refuse to accept them as a band

"Spiritual" - He's a ghost

"Hearable" - They're here just to play music. That's their point in "life," such as it is.

"Ya'll can see me now cuz you don't see with your eyes" - 1) he's a ghost and you need a 6th sense to see ghosts 2) the point of Gorillaz is pretending that they're real

All-in-all, it's a weird, darkly humorous song by a British group. No drug abuse. No dark meanings. It's Brits being Brits. End of story
