Ok. this could go to games, but I thought it fit here.

I was thinking if we could fit a song to each champion.

Rules to prevent stupidity and chaos:

Awesome is not a good reason
Has to at least vaguely relate to lore (welcome to the LORE page).
Leave a link to youtube.
Does not need to be original artist.
Rather the music be RL.
Prefer not Fan made music made for a champion or the game.
Explanation would be nice.

Just two to start this out.

Karthus: This Corrosion by Sisters of Mercy (prefer cover by In Extermo) http://www.youtube.com/watch?v=bNUrJBvKf_I
Singing Corrosion and it is a bit sad. it is a song about being left behind. Karthus is ultimately left behind. That may be how he came to be.

Nocturne: When You're Evil by Voltaire (I like the Freddy Kruger version) http://www.youtube.com/watch?v=vL8a0oj77x4
Who better? He is a ghost bent on torture til we go crazy. The last part when the song goes sad is kinda like his ult. "Aww no one loves me and I'm lonely. Can I get a hug??" Teemo says, "Sure!" Nocturne rips out his spleen.

Draaaaaaaaaaven. Title: Perfect gentleman. Self explanatory

PS: "When you're evil" fits Veigar more. Noct needs smething darker.

PS2: this one is in spanish, but fits Twitch so well!

Now THIS fits veigar! or maybe Karthus.

Alright....didn't expect my favorite comic character to make it.

Self-explanatory.

In fact, pretty much any DLC song can be applied to her in some way. It suits her so well.
