Actually i think the power of the music is in it's frequencies. I always loved instrumental music, because it is universal, unlike lyrics, which are limited to the human that can understand the language they are written in.
Unfortunately many lyrics of these times are pure trash. I mean, telling our young generation that the world is only about sex without love, drugs/alcohol and party can't be positive at all. (Note to self and others: Don't hijack this thread and steer it into the*youknowwhich* direction please)
Sometimes there is music, which has some really good lyrics, that do have some real sense. Those are lyrics i like.
Lyrics (singing) can also add a whole new dimension to music, as it could be seen/heard as another instrument - the voice. My music was almost always only instrumental, but that was because i can't sing and had no singers to team up. I noticed, a singer can turn a 'boring' or 'empty' song, into something that becomes alive.
So, yes i like lyrics, but it really depends a lot on what they are about.
But i could also just listen to pure instrumental music aswell, without missing anything.
