Writing using sometimes

Prince’s song “Sometimes it Snows in April” is a poignant piano ballad about the loss of a friend. The song hinges on the use of “sometimes” in the chorus:
​
Sometimes it snows in April
Sometimes I feel so bad, so bad
Sometimes I wish life was never ending
And all good things, they say, never last
And love, it isn't love until it's past

The use of sometimes deepens the resonance of the song. Prince’s speaker isn’t “always wishing life was never ending”, which would make his character harder to relate to— what kind of person is always wishing to die? Instead the “sometimes” humanizes the speaker—they are easier to relate to. After all, who hasn’t felt that way some days?

Likewise to how it sometimes snows in April, the speaker sometimes feels so bad. There is depth and nuance that comes up from the song. It’s the difference between someone who is always drunk, and someone who sometimes is drunk.

Think of the things you sometimes do. Do you sometimes get a cup of coffee? Do you sometimes talk to strangers? Do you sometimes have trouble getting to sleep? How can you use “sometimes” create meaningful characters in your songs?
Good luck!
