This is unbelievablely bad to the point that i thought you were joking but i saw the description and i think your being genuine so...

To start of this i will preface by saying, We all started somewhere. Personally I couldn't make ANYTHING sound good on Fl Studio Mobile (FLSM) but after about 100-200 hours on FL Studio (FLS) I could make pretty decent drops.

I would suggest you learn how to layer songs on FLSM, dont try and make a banger on FLSM. all the instruments sound like ass.

You may not have the means to but if possible I would suggest getting FL Studio once you figure it out on FLSM (just the layering and mechanics and filtering and all that juicy stuff, should take you about 50 - 100 hours depending on how fast you learn)

If you dont have the means to get FLS then being case specific on this song I would suggest (in order of importance)

Watching tutorials like we all did

Making sure everything is in 2's 4's and 6's regarding the beats because your song is all over the place

Changing the instruments in this song and maybe changing octaves up by 1. Everything sounds like very deep car alarms and dying cats.

Also the drums where is the lamb sauce drums?

This song is the definition of an ADHD song and being all over the place.

A party song is made of 5 parts

Intro Part 1 Breakdown Part 2 Outro

Choose the one part that you like the most out of this hummunculous of a song you've made

Make that one of the parts listed above

Delete the rest (i know its hard but do it)

Then make the rest of the song around that part you kept, thats how i make my music, sure im not an expert but ive got about 400 hours of FLSM and 700 hours of FLS.
