Can you pick just one song...

No, I haven't heard any such song that represents my entire true identity.

The song "Water Woman" by Spirit (also covered by one or two other bands) has a lyric that represents my true self:

"Water's the only way, water's the only way, follow the fish today, see what he has to say".

You see, I am the fish.

Nope.
