Go into the studio and click on the title of your song on the bottom of your screen in the middle and click yes on the remixes when it pulls up the place where you can name your track and give it a photo. Then it should work.
I suggest less on the bass it is a little too heavy and it covers everything else. I would also try to be less repetitive. Like in the middle completely change it up. Like when you hear a song on the radio it's not the same thing over and over for 3 mins. They have different things come on and off during different parts of the song. I like the part where you silenced the bass for sec. I wish I could remix this. But other than that not bad.
Yes. I really wish I could remix this. I can't explain what I am thinking of it or what I could do with it. it's something that you have to hear in order to do. or understand it.
