If I happened to listen to any music before bed, it'd only be instrumental. I can't STAND having lyrical music stuck in my head at night...it'll just keep playing over and over again in my brain and then it makes it hard for me to sleep.
I have a playlist that I play before bed
Keep Sake- State Radio
The Trapeze Swinger- Iron&Wine
Yellow- Coldplay
The Simplest Thing- Hey Rosetta
Possibility- Lykke Li
Going to California- Led Zeppelin
I have tons more, those are just some of my favorites
It depends on what I'm in the mood for. I usually have music playing while I sleep so I'll either put all my music on shuffle or else pick albums or songs from certain artists.
Not one thing wrong with Castlevania music before going to sleep
For me, I usually break out either really old Church hymns (gotta have my Anglican hymns), oldschool modern Christian music when it was, err, better (like LeFevre or Dion or something), or maybe some Fleetwood Mac
