Love that sample, but it sounds more like "melancholy gay zombie" to me. Could use just a tad of a pick me up in tempo if you're going for happy. Subtracting half a star for the abrupt ending. Other than that, great tune. The bass is throbbing in my ears, possibly lending to hearing damage, and it's amazingly catchy. Would liked to have heard more hints of the sample throughout, and possibly more whooshy transitions. Nice work!
