Bit of ambitious thread, but fuck it. I've been listening to Destroyer's Rubies a lot again recently, and realised that it contains so many of my favourite melodies - the wordless choruses in the title track and European Blues, the riff at the end of Painter in Your Pocket...

Another example would be pretty much all of Hard to Explain.

What melodies do you never get tired of hearing/seem to be permanently stuck in your head?
