I don't see how most of these songs have anything to do with helping a person build or create new things. Lets have something ambient that doesn't have lyrics for once. A song that can be used as a base to create your imagination onto.
In that case:
Sanctuary Fortress - MP2 Echoes
Torvus Bog Subterranean Area - MP2 Echoes
Skytown - MP3 Corruption
Staff Credits - Metroid Fusion
Underwater Depths - Metroid Fusion
Prophetic - Tetrisphere
Maridia - Super Metroid
White Bounty - Rexy
Drowned in Exile - Children of the Monkey Machine
Dimstar - Beatdrop
Brinstar Depths - SSB Melee
Tallon Overworld - Metroid Prime
Phendrana Drifts - Metroid Prime
Metroid has some good ambient music...
On another note:
Still Alive - Portal
Kindred OCR - Pixiesticks/Zircon
Sally's Song - Amy Lee
Hello - Evanescence
My Immortal - Evanescence
Give Unto Me - Evanscence
Automatic - Electric Valentine
No - Vim
Triple Baka - Hatsune Miku
Matryoshka - Hatsune Miku
The Last Judgment - Masayoshi Minoshima
Suwa Foughten Field - Masayosha Minoshima
