BTD5 Music in BTD6

What if BTD6 was actually released to the public? That okay, but all the music for the tracks will increase file size drastically! So that's why I'm conserving music from BTD5 and Deluxe into Bloons TD 6 tracks. (Special Mission/Unique tracks don't count.)

Examples:

Monkey Lane - Jungle

Park Path - BTD5 theme

Lightning Scar - Desert

Ocean Road - BTD4 remix

Bloonhenge - Rock

Floating Islands - Space

Tracks that go in here must:

Have a picture.

Have the link to the correct song for the track.

Must not be a Joke Conception.

Must not be a candidate for deletion.
