A song is a set of lyrics accompanied by a tune. A good song should provide an adequate amount of emotion while not overpowering the listener. However, not all songs are created equal. Some are mediocre and are more about the melody than the lyrics. https://songtexte.bz/

A lyric is a short poem used to convey emotion. The word "lyric" derives from the Middle French word "lyrique". Traditionally, a lyre is a small stringed instrument which is played while singing.

The lyric is usually a verse, but can also predate the tune. A lyric is a combination of the eloquent words and the technical marvels of rhyme, alliteration and meter. A lyric is not only a creative expression, it's also the intellectual property of the lyricist. The best lyric can reference the feeling as well as the melody.
