If you want to play along with an original recording as a backing track, you may want to look at the Moises app.  It allows you to remove (or significantly dampen - you choose what percent) the guitar part from an original recording. And then save it as an mp3 file.  I’m getting a real kick out of playing Day Tripper with the Beatles, Satisfaction with the Stones, etc ….  Not only fun, but I’m finding it a great practice tool to work on my timing.  Ringo is my drummer!
