Just heard this today, thanks to Pitchfork's Top 100 Tracks of 2012 list - lovely stuff.
Waves won't break 'til the tide comes in.
Introduced to me by a Welshman. Real ear worm.
I love this song only slightly less than my 2-year-old boy.
I know everyone else has already posted this, but it's taken me a while to realise how great it is.
