Hello @SoundOfMind
Andi, as well as myself, are just other musicians, like yourself. We’re here to help and can answer some questions, but sometimes we don’t have the answers or aren’t sure, and thus, need the help of someone from iMusician.
Please be respectful and patient (remember our guidelines: How it Works! 🎶). Your post is only from yesterday and it’s a free forum. You can have an answer between a day and a week, depending on the schedule of the staff.
As far as iMusician is concerned, you can upload your tracks anywhere you want. The contract is non-exclusive. However, you should check the other platforms you mentioned and see what their distribution agreement is. Maybe they’re non-exclusive too, maybe not.
I’ll ask @Carlos to confirm instead of Maurizio.
