Although lyrics may rhyme, there is no reason that they have to. If you choose to rhyme your lyrics, be consistent and rhyme all lines (don’t mix and match rhyming and non-rhyming lines). However, when rhyming, be don’t just put words in a phrase because they rhyme; think about the actual meaning you are trying to get across. Just because words sound neat together doesn’t mean that they make good lyrics. In addition, to avoid being tiresome and predictable, be wary of employing over-used rhymes, such as "love/above" or "heart/apart."
