There are different platforms, sites, applications and programs for music. I most often use itunes and apple music. To promotion in these applications, I can advise you on this service
https://smoservice.net/itunes/applemusic/ . I’m just starting to learn SMM, but I have already seen a lot of good reviews about this service for other social networks on the Internet, on different portals and forums about SMM. It seems to me a quick and effective way to get more listeners for you.
