Where Do You Check For The Latest Songs Released Today?

I'm mixing fresh singles and reupping them but my competition always beats me to it. Are there any websites you check to see the latest singles or when an artist uploads an audio version in their YT channel? And I mean like instant updates or only hours of release while the demand is hot. I've tried mtv, billboard sites but they don't that, I don't know why they wouldn't have a list of the freshest singles, even itunes doesn't have one.
