See, the thing is, as headers or enders, lyrics work fantastic. Splicing them in however, is what happens when you try to get the same effect as a song in a movie, and I feel writers pain, because I'm tried and failed to do it as well, but there is just no way to it in the way that tv or film can.

So, please STOP TRYING.

And I feel your pain. Writers need to focus on the really important things, and minutiae, unless it's used as a metaphor, usually isn't that important.
