Nothing Is New
Anton Chekhov's old adage that "there is nothing new in art except talent" has never been more true than in the hyper-connected world of modern music. There are precious few new ideas, sounds, or techniques to be applied to the creative process, and those which are discovered are quickly copied and pasted into a thousand DAW projects.
The 'newness' to be found in modern music stems from the unique personalities, perspectives, and influences practitioners are able to express in their art. You should never be afraid to steal ideas, the trick is to take from a wide variety of sources and then make the resultant amalgamation your own.
