IMHO, LOL ACRONYMS
Great song, reminds me of those crazy sephora songs like "Living Hell" on the subject of ideas. I think you should end it with that big scream at the beginning, but only the scream, very minamalist, maybe only a few things, but the scream is the most prominent part. I think that would put a strong contrast between the rest of the song which is all crazy and loud and full of noise and the end which is the opposite. I'm not a music making guy though so I wouldn't really know, whatever you do is golden anyways so it doens't really matter.
On second thought, just cum onto the mic at the end, becuase when I finish listening to this song I'm spent LMAO LOL ACRONYMS.
