Some people I talk to can't sing along with their favourite albums 'cause they don't know the lyrics. This puzzles me. I tend to know all/most of the words to most songs by my favourite bands, and random bits and pieces here and there to almost everything I listen to. Ask me to write down pretty much any song by Dark Tranquillity, Tiamat, Iron Maiden, Slayer, etc. off the top of my head and I'm pretty sure I can do a decent enough job. This is not because I consciously study the lyrics, but something that comes with plenty o' listens and the occasional glance in the booklet. How about you?
