Can anyone recommend a service to me with a large music database? It's actually a challenge to find some songs 

Well, I use Amazon music, and for me, it's pretty good. But most of the time, I just listen to pop music, and that's it.

I used to struggle with that as well, and I can tell you that for me, the best solution turned out to be listening to music on Youtube. Well, now I just download songs with Tubidy, and I can say that it's not a problem for me to find all my favorite tracks and live performances there, so I think you can give it a shot as well if a large database is actually important for you, I'm sure you won't be disappointed.

It seems to me that the biggest music database is centered on the SoundCloud platform. Because only here you can find exclusive music that is not found anywhere else. I advise you to take note of the SoundCloud promotion if you want as many people as possible to know about your work. Buy likes, followers and your musical creativity will be a great success and popularity!
