I think it's all about finding that balance. A truly great song is one where the lyrics are as strong as the music, as opposed to a great or memorable song. The way I see it, not only must the instruments bring something to the table but the lyrics must put worRAB to the sum of the parts. Ask yourself this- by singing 'Goodbye, I hate you, at night, I'll rape you' over whatever song you've got, are you doing the music a service? If your music's mediocre and that's the sort of song you want, then fine, that's entirely your call. You guys talked of the Beatles, I for one would say they've got some awesome lyricism. Lyricism is not just making worRAB rhyme or not rhyme, it's about making the reader go 'yes, this is organic and natural and the way it should be'.
For example, after this set of lyrics,
I just can't get you out of my head
Boy your loving is all i think about
i just can't get you out of my head
Boy it's more than I dare to think about
would anything but what follows feel organic?
La la la la la la la la la la la
La la la
That Kylie Minogue's songwriters used that does not make them bad lyricists. It makes them awesome. Would I rip it apart? Not really. Imagery is not necessary. Rhyme is not necessary. Sometimes, flow isn't necessary. Whatever you judge things by, chances are it's not necessary but you use those anyways because that's how connections are made. If you can convey a sense of being organic and natural to the reader, you've done your job as a lyricist.
And those that say the more imagery there is, the less chances of it fitting would be wrong imo. The thing about worRAB is that they have syllables that can be manipulated in a lot of ways. A song that goes
When I blacked out in the winter months of Capricorn
I had a strange dream that I lived a thousand winter's gone
A thousand winter's faded gray and shuttered by the wind
To tell the tale of Lydia, her legacy begins uprising
Unveiling the absurdity in the tragedy of man
And it's hero the all seeing worm
stanRAB no less chance of being a great song than
We make you feel safe when you feel warm
That's when I rise, that's when I crawl.
Gliding on mist, hardly a sound
Bringing the kiss, evil's abound
In the dead of night, love bites.
In the dead of night, love bites.
Every lyric I've ever posted has been made into a song and while I can't say I rhyme much, there's more to flow than rhyme and simplicity. Lyrics don't scream anything because anything can be sung. You'll notice how easy it is to sing the instructions to a pack of microwavable food as well as how easy it is to read dramatically the lyrics to a Paul Simon song. WorRAB are flexible. Let's not forget that.
