Unless you have permission from all parties, it is not possible to distribute music with uncleared samples.
You are allowed to upload remixes and DJ mixes of your own music. But if your remix is of another artist's song or contains any part of another artist's song, streaming services require that you have written permission from the original artist.
If you are uploading a remix of your own song
You don't need to credit yourself as a remixer. You would just need to set the album or track version as "Remix."
Under the song title preview, it should show up like this:
Song Title (Remix)
If you are uploading a remix of your own song by another remixer
You should add "Remixer's Name Remix" as the album or track version. Additionally, you should also add the remixer under the songwriter's section and choose the option "Remixer"
Under the song title preview, it should show up like this:
โSong Title (Remixer's Name Remix)
If you are uploading a remix of another artist's music
Note: You must have permission from the artist to do this.
You should add the original artist as the album or track's main artist. Additionally, you should add yourself under the songwriter's section with the "Remixer" role.
Under the song title preview, it should show up like this:
โSong Title (Your Name Remix)
Important: Do not select the "Cover song" option in the "Songwriters" section, as remixes are NOT cover songs.
