If you use a song in a story- like it is on the radio and you quote a few bars, then acknowledge the song and the artist.
What they are interested in is selling albums and every little bit of publicity helps.

Close to the edge, down by the river.
Down at the end, round by the corner.
Seasons will pass you by,
Now that it's all over and done,
Called to the seed, right to the sun,
Now that you find, now that you're whole -
Seasons will pass you by,
I get up, I get down -
I get up, I get down -
I get up, I get down -
Close to the Edge by Yes
