Is it not possible to have two podcasts? Or two music lists? 
This is a forum for code issues, Wix Support would be best suited for your questions.

Ok, but It dosen’t say, that’s why I ask here.
Okay, I understand, however this is for code issues, anything else should go to Wix Support.

Just look through Wix Support pages and you will find…
Currently, it is only possible to add one podcast app to your site.

Playlist : You can have up to 100 playlists with up to 500 tracks per playlist.

Otherwise I guess I have to create two different Wix-accounts, so I have one podcast on one site and one on the other. ?
@givemeawhisky Aha, thank you!
(I don’t know what you mean with code issues though… The Support is not a discussion forum. Why can we not talk about anything related to Wix website building here? I mean if the support dosen’t say what you need to know. Sorry for my poor English.)
The forum is called Corvid by Wix.
Which is Wix Code, so if you have issues with using Wix Code then you ask here.
this is Wix Corvid.

Contacting Wix Support or looking through their support pages is for everything else not connected to Wix Code issues.
Also, Wix Support can be a discussion if you contact them by phone or put in a ticket and wait for their email reply and then email them back!
Vote for this request here and it might get added to Wix sometime in the future if it gets enough votes from people.

@givemeawhisky Ok. Maybe it’s possible to vote for a request of a discussion forum about anything related to Wix websites.
