Was a prerequisite writing your own material, because about 98% of country artists would be DQ'ed
This has never made sense to me either, you would think country would be the most authentic genre but it's definitely not.
Suppose it depends more on the era. I don't know as much about the 2000's the present. Of the old country legends- e.g., Waylon, Willie, Hank Sr and Jr, Merle, Johnny Cash - they wrote most of their own material.
Somewhat, Waylon had Billy Joe Shaver write most of Honky Tonk Heroes album. Kris Kristofferson wrote alot of stuff for other artists. What ever you may think of Toby Keith, dude writes alot of his own material. Very rare these days.
Chinned for knowing your shit on honky tonk heros which is my favorite country LP of all time. Top 10 album for me of any genre and yes it was all Billy Joe Shaver. Waylon did right a number of his own hits like "This Time", "Rainy Day Woman" and "Are You Sure Hank Done it this Way". He did cover a lot of other songwriters of course.
Merle and Willie by the way were both prolific songwriters. Cash wrote a fair bit too.
