Helpful hints for trimming down overweight songs:

Is your intro twice as long as it needs to be?

Do you even need an intro?

Verse two...are you sure you don't want to go right to the chorus instead?

In between verses, are you playing a transitional passage that's the equivalent of paddling an oar in the water? Is it really needed, or can you just move right on to the next part?

Verse 4...sorry, your screener never made it that far.

Bridge...I love them, but if you're trying to pitch a song for airplay, bridges are often just another bit of bloatware.
