Not always, but this one is---Midnight Rider, by the Allman Brothers. I have known and played the song for decades just like the original album track, and it's so easy to hear the changes. I was checking after I saw someone play it a little different than the original, in case I was wrong. Unbelievably, though, EVERY site I saw it on online is WAY wrong. Even tab sites for guitar or bass, the same. How in the world can anyone get this song so wrong? I even listened to it again to make sure I hadn't misinterpreted it myself, but no, I'm right. The biggest mistake I saw online was the use of Am7 instead of C, and then Gm7 instead of Bb. It's just ridiculous. Of course, I've seen things like this with other songs online, too. I can forgive little discrepencies, but Midnight Rider? I mean, come on. Sorry had to rant somewhere about it.
