Ok i'll tell it in my personal favorit style that hurts my eyes:
What do i search for "cave":
In this subject i search 1 song who can be used in 3 types of themes. An forest cave, this includes a bit muddy but still a nice warm cave (or if mud gives you the chills that works fine for me too). A plain cave, this includes the main type of cave, since my caves are mostly only for bonuses it has a nice clay brown colour. And as final the wet cave, this includes water and fish!
What do i search for "forest":
This one is pretty easy. I need a song for a forest with a nice feel onto it. Not too hasty, not too slow. A nice song that gives you a feeling like: "Welcome to the forest pardner!"
What do i search for "sea":
A slow nice song that wants you to play and stay in the level instead of making you barf more than the original did (i hate water levels but love water haha).
What do i search for "plain":
I want a song who tells you: "Welcome to this place! Enjoy yourselfs.
What do i search for "castle":
I need 2. 1 for a castle and 1 for a ghost house. I know a ghost house isn't a castle but it has a save prompt so i do count it! For the castle i want something serious! Something that wants you to fight the boss like it is the final! (iggy XD). For the ghost house i want something halloween, spooky or something realy slow but not yet nice.
What do i search for "chalange":
Something hasty, cool, pumps you up and ofcourse AWESOMENESS!
What do i search for "nice":
Since sticker bush symphony is a nice song i think it is overused alot. I want something instead of that one.
I hope this makes it clear for you? :3
(ps: if someone has something for the overworld. Plz add that too ^^)
