+1 To battlebards I not sure if someone has mentioned this group uet, if not I would be very surprised, but these guys have been creeping up the ladder of dnd tablesounds for the better part of a year, while their service has just launched they have a metric orc ton of backrooms music and sounds, honestly they have stuff that you might never use. And on top of it they have an awesome sound mixer that let's you make sounds tracks they fit a scene perfectly, while this adds to prep time, the possibilities are endless, you could have a surly dwarf shop keeper get hit by a fireball, turn into a werewolf because reasons, then get eaten by a pixie, your game your rules! Now I'm not sure if I'm allowed to link, but really guys I would have you check them out, combined with roll20 it could be the best thing to hit gaming since.....well you get it.
