These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Willie Nelson
Awesome Music: "Always on My Mind" was his biggest pop hit. "Angel Flying Too Close to the Ground" and "My Heroes Have Always Been Cowboys" have also been cited as his best.
Not to mention his duet with Ray Charles on "Seven Spanish Angels".
And, of course, he wrote awesome music for other artists, most notably Patsy Cline and "Crazy".
Signature Song: The aforementioned "Always on My Mind," "My Heroes Have Always Been Cowboys," "Angel Flying Too Close to the Ground," and of course, "On the Road Again." Really, who doesn't know that one?
