Also annoying is playing along with songs that are just a hair off of standard. "Jesus Just Left Chicago" is one for example. I found after tuning to the song and checking my tuner, it was around 443hz...close, but far enough off to make you cringe. The A string is also dropped to G...that I wouldn't mind...but having to redo all the other ones too is such a hassle I'll usually skip it when it comes up on my guitar playalongs playlist.
