As the topic asks, do you think non-hip-hop song lyrics need to rhyme? I've noticed that a lot of older metal bands (Metallica is the most obvious example) make their lyrics rhyme, but it always sounds awkward and forced to me. With line length generally being shorter than those of hip-hop verses, and the better hip-hop artists (Eminem, Cole, Lupe, Nas) creating multi-syllabic rhymes, internal rhymes, and complex word-bending to make rhymes happen, the rhyme patterns/rhymes don't come across well. And when I've listened to bands' music that don't constantly force rhymes (Coheed, Opeth, Vulvodynia, Infant Annihilator), it sounds better to me and isn't distracting.
Am I just weird on this one? Am I overthinking this (pretty likely...)? What do others think?
