Epic MapleStory find (Sleepywood music on Sirius Satellite Radio)

In all honesty, when I first heard it, I would not have thought "sleepywood music". I had to listen to it again to <kinda> hear it... Thing with music is that there is so much variation possible that it could've just been a coincidental thing. Then again, music at its roots (chord progressions) commonly use the same things so it wouldnt be surprising if they were built on the same basic foundations, hence why they kinda sound alike.

Or it could be written by the same composer.
Composers often 'recycle' certain passages in their music.
