Back when people could actually sing. Theses days anyone can be an "artist" abeause of all the voice machines. I like older rock n roll.
Now a days if a person doesn't sound like, them strangling a cat, everyone thinks they are a good singer. You can sound OK, but be bored to death by them. But on the other hand if you don't have a great voice, but apply it properly it can still be successful singer, not an adequate singer. You got Bob Dillon, Janice Joplin, Fiona Apple, Joe Cocker and so on.
