I think it's not that hard to build a big music database anymore. Many music publishers have been willing to rent their music catalogs since streaming became so popular. And Voxxo already has experience and contacts in the music business, so i am sure, that we will have many great musicians in our playlists.
That might not be true for all music genres and various music. But you are right. Technology has developed so much and it might be easier to create such database than what I think. Voxxo definitely have experience and they might have clear idea about how to handle such things.
