there often appears to be a lot of jealousy involved towards new performers singing their own material

While I'm sure we have all heard words we would have like to have (or to have been able to have) written, I can't say I've ever been aware of anyone being jealous of a song that bores everyone else to death.

To my mind, an honest introspective navel-gazing self-penned effort is often more entertaining than a safe but uninspired rendition of a well-tried classic.

Not to mine, I and others can at least sing (if only to ourselves) to the well tried classic.
