Surprisingly calming. Play this with ambient music for maximum effect. I suggest the Toonami OST

I had fully intended to try to stand up for this side of the Atlantic, possibly with Nightwish's 'Nemo', or Snow Patrol's 'Run', but actually that was bloody good. Touché.

i always get a chill whenever I hear this.

Tool's 10,000 Days actually has the sound of rain and thunder in the background during the song's opening, it was written with that in mind. It's one of my favorite songs in the world.

This is perfect

it's just an instrumental of a song, but both are pretty relaxing, and i'm sure they'd be even more relaxing with rain
