Likewise, his song "You Don't Love Me Anymore", in which he expresses that he gets the impression his significant other, well, doesn't love him anymore, citing the reason for such suspicious as being things as poisoning him, holding up a knife, putting piranhas in his bath again, etc.
The Beatles, in "Come Together", gave us such enlightening information as "He's got feet down below his knees" and "One and one and one is three". You don't say.

Nothing you can do that can't be done, nothing you can sing that can't be sung
Talking Heads' song Once in a Lifetime has the lyrics "there is water at the bottom of the ocean." Obvious statement much?
So Yesterday by Hilary Duff states that "If the light is off, then it isn't on" and "You can change your clothes (if you wanna)". No, really?
Forever Young from the second Care Bears movie includes the line, "You'll be with me until/The sun shines through the night./It never will."
Clearly someone's never been to the North Pole.
In ''Bad' by U2, Bono sings at the top of his lungs, "I'M WIDE AWAKE! I'M WIDE AWAKE! I'M WIDE AWAKE!" then softly croons the brilliant corollary, "I'm not sleeping." Yes, I gathered that.

Lil Wayne seems to like being Captain Obvious. For example, in I Can Transform Ya he says, "I Can Transform Ya/ Like a Transformer". In Mrs. Officer the guy singing the chorus sings, "I can make you say, Wee-ooh-wee-ooh-wee, Wee-ooh-wee-ooh-wee" and Lil Wayne chimes in with, "Like a cop car".
In "Total Trash," Thurston Moore from Sonic Youth insists "it's a natural fact that I'm not no cow."
Jonathan Coulton in "Betty and Me", on the subject of genetically engineered children:

He also does this at least once in "Madelaine":
If it doesn't kill you, it'll make you stronger But if it kills you, you'll be dead

Turisas's "To Holmgard and Beyond" gives us this enormously helpful elaboration in the spoken-word bridge:
Threads of different lengths. Some longer, some shorter.
David Bowie's New Single "Where Are We Now?"' features the line "the moment you know, you know you know". It makes some sense given the overall song but still sounds remarkably obvious when its actually said outloud.
The Postal Service's "We Will Become Silhouettes:"
"Until our shells simply cannot hold / All our insides in, and that's when we'll explode... / And it won't be a pretty sight."
