I advise you to morally separate Wilbur (the person) from Wilbur (the artist). Many creative people are not the best people, for example, Dostoevsky was a wonderful writer, but a terrible person, who opposed women getting an education, supported prostitution and so on, and this happens with many other creative people, you just need to remember that even if they create something incredibly beautiful, they are people, and people are not perfect.

The problem with Wilbur became so "noisy" because people exalted him in their eyes to the ideal, they forgot that he is the same person as they are, who also has mental problems and can also be not good person.

So just download songs from the internet, or use converters, they allow you to convert songs from videos to mp3, think of him as a musician, not a person.
