Seven Swans had me at hello. The very first line of the album is, "If I am alive this time next year...", which is such an amazing lyric; then it just keeps getting better.
I often forget how important a first line of an album is, that's a good one. They always say how important first impressions are in life, why should music be any different? That'd make a good post "best first lyric". I've always been a fan of Put your hand on the wheel, let the golden age begin
For best first lyric I'd probably go with Van Morrison - If I ventured in the slipstream / Between the viaducts of your dream / Where immobile steel rims crack / And the ditch in the back roads stop / Could you find me?
It's a good one. Was it you that mentioned this album a couple weeks ago in a comment? It's a good one.
