I guess I haven't ever thought about it to that depth, but I pretty much agree. I don't like most of my favorite players' influences. Slayer for instance...they loved early punk. And Billy Gibbons (a renowned blues historian/connoisseur himself) goes to the roots of the blues all the way to Africa with their tribal music.
Then again, you might listen to anything "old school" and still take it to your own next level, regardless of another's previous results.
