I am a bit.. Oh how to put this... anal when it comes to music when I am rping.

I have play lists worked out like one may outline a chapter in an educational text...

Over Rp Feel
-Character In General In Said Rp
--Specific Feeling For Said Character In Said Rp

Each character I have has these play lists and sub play lists. Then I have just general RP Playlists divided up by Rp type and scene (fight, meeting, traveling, etc) - As well as specific "The Feels" playlists (sad, happy, funny, serious, etc.)

Having said that there are common bands or singers I gravitate towards when building a list - Amaranthe, Fleetwood Mac, The Eagles, Kamelot, Cradle Of Filth, The Misfits, Rush, Johnny Cash, Bette Milder, and so forth.
