Ok, so I have some ideas for y'all. First off, you want to rhyme. Whether the rhyme is inside one line over over 2 or 3, you want one. They are ofter represented by symbols.
For example, this would be an AABA Verse.

You're asking me will my love GROW
I don't KNOW
Ah, I don't KNOW

all the words in capitals are rhymes. Also you can have rhymes in one line.

Hey hey momma say the way you MOVE, gonna make you sweat gonna make you GROOVE.
-Black Dog, Led Zeppelin

That was a great song. Also if you need help use a rhyming dictionary. If you don't happen to have one, use Rhymer.com.
