"I used free downloaded beats or uncleared and recognizable samples on my song or I have remixed/created a low-fi version of another song and I want to upload it to stores. Does that have any

Yes, some platforms that generate revenue do not accept free beats, remixed songs or low-fi versions. So even though we'll deliver your song to all of our partners, some major ones will reject it. For example, YouTube is a major platform that won't accept free beats. You songs will, however, be delivered and accepted on others that don't generate revenue.
