I am a support main. My second best role would probably be mid.
I typically play aggressive supports(thresh,morgana, leona, etc.). I will play almost anything that has some sort of stun pre-level 6.
I have been diamond since summer of last year(Season 3).
I mostly listen to Pandora when I stream. You can look at the playlists here :
http://www.pandora.com/profile/stations/echuchee. I listen to just about anything
I also occasionally play a bunch of YouTube playlists.
If you have any questions about League of Legends(especially supporting) feel free to ask in chat!
