Some great albums already mentioned on here - the Cure, Marvin Gaye...wow
The album that towers in my life - simply because it unexpectedly came at the right time and its lyrics set off a chain of thoughts that ended up with me eventually breaking free mentally from the chains of the JWs is Darren Hayes' very electronic 2004 album The Tension and the Spark. One of those albums I bought then never actually listened to until a couple of weeks later. Couldn't believe it from the opening lines of Darkness ("been spending so much time underground, I guess my eyes adjusted to the lack of light...I was covered in darkness") to the spiritual/fleshly war described in I Like the Way ("the decadence of giving in to desire creates such entropy within - looking for love in spiritual faces, blind to the art of fabrication..."). This was an album speaking to ME!
To this day I'm still not sure why I bought the album in the first place - I always found him and his group Savage Garden as saccharine and whiney. It's a shame he went back to the whining and the saccharine with subsequent albums but for a moment Darren Hayes had something genuine to say and he said it very well.
