Yea, i remember back in the early day of the internet, coming across a thread that there are huge massive 'song houses' that have thousands of song already written and artists access it through the recording company - iirc a single norwegian ran music house had supplied their tracks to dozens of top recording artists and the artist literally just changes a word or two to get the writing credit - but the company takes a percentage in perpetuality and there are several companies that supply written lyrics for every type of genre, and situation etc. It's highly manufactured at the top - nothing is truly organic. Look at that other country singer from a couple of months back - he didn't even write the song that was causing all the furor.
