What makes a song appealing? Is it the emotion it provokes in you, or perhaps the way it makes you want to dance? Such aspects of a song can be contributed primarily to rhythm and rhyme.
For example, a dance song will typically have an intricate rhythm with a light subject matter. Ballads tend to have a heavier subject matter accompanied by a simpler rhythm. In songwriting, the tendency to want to rhyme everything can produce lyrics that don’t make sense or don’t express what the songwriter is trying to say. An easy solution to this problem can be using “near rhymes”, words that have a similar ending sound, but do not necessarily rhyme in their entirety; for instance, instead of rhyming ‘forever’ with ‘never’, you can use a near rhyme with the word ‘together’ as both words have the same ‘-er’ sound at the end.
