My biggest peeve about backing tracks is when the band has laboriously long programmed intros in all of their songs and stand around looking at their shoes while the tracks play.We use them all of the time but as support for the band, not to replace instruments. If it's not on the stage, we don't have it in the backing tracks. I really don't pay much attention to them while playing, I'm more into the song and the moment.
If you're a solo act, there's probably a little more grace for using other instruments in the backing tracks. Depends upon the scenario and what you as an artist are trying to create for your audience. Any attempt to fool the audience wouldn't sit well with me personally, it's akin to lip-syncing.
Hint, if you look bored, so are we!
