Haha romper! thats my favorite method.
Lyrics and music can be a very tricky thing. They are two different forms of media/art, and to combine them succesfully while being sincere and relevant to the song can be difficult.
Personally, i enjoy music where the lyrics are integral to the song. I cant stand it when lyrics are an afterthought, or just put on becuase the artist expects that the only way to present a song is with lyrics.
I am a big fan of instrumental music. For me, a well wrtten song can have all the meaning you might need.
For example, modernist composer Olivier Messiean is a perfect example of this. The context is that Messiean was a devoted catholic. He was a synisthete and had visions of christ and the wonder of catholisism. Now, im not religious, but with this context in mind, his organ works convey the dedication and wonder he expirences from Christ. Sweeping melodys, haunting passages, modal manipulation, Attonal terror and release and the overall splendor of the church organ more than project a tiny peice of his vision. A single church organ and nothing more, as with Bach's organ peices as well. Lyrics would be irrelevant, if not damaging to Messieans Organ works.
Lyrics are not a crutch however. Some of my favorite music contains lyrics, and when the message and delivery matches up with energy and context of the song, the results can be quite good.
Make sure that the songs power matches up with lyrical content, and that the rythm of the lyrical presentation will compiment the song, not be seperate from it.
This argument, of course, is abandoning the human voice as an instrument. which is a different argument all together.
The question also remains, is a song just a platform for sung poetry, or is it reversed?
And in the end, who cares? If you can feel it and it stirs your soul, it doesnt matter what you do lyrically. Dig dem Jams!
