I don't like it so my opinion is that he's wasting his abilities playing crap songs.
Then you're a close-minded idiot. What you might think is an amazing song, others will think is a crap song. Now stop being so self-centric and learn to accept that any sort of art's perception is based almost entirely on those who are subject to it.
If you can't comprehend; Its a good song, just not to you. And you don't have to listen. The effort would only be wasteful if he did nothing with his talents.
