Haven't read much of the recent posts, but I sort of resent covers. I love doing them, but I hate spending a couple hours recording a cover and it getting hundreds of thousands of views, meanwhile my original songs, which I spend days/weeks writing and recording just sort of fester and get like 90 views. It's a little disheartening and shows the effort gap. You don't have to market covers nearly as heavily as original music. The fact that it's known material sort of gives it a pre-baked amount of exposure.
