WOW!!! That Bandstand tutorial was unreal. Unfortunately being in the obscurity of somewhere between beginner - Intermediate level, I think it is well beyond my needs. Man, I wish I started playing 30 years ago. Damn sports! C'est La Vive. That said, rather than continue to use Microsoft Groove Music player, which has served my purposes well-enough thus far, I am going to VanBasco as recommended.
If I understand correctly, instead of trying to find a track I want to play, minus the guitar track (rhythm and/or lead) I can download the full version of the track and remove (mute) whichever portion I want when I want, i.e. lead one time through, rhythm the next, correct? If so, this is great at this stage of my learning and ability. For example, for songs like American Woman (the Guess Who) I can let the rhythm flow while I try the lead. Although, I really do like just grooving that songs rhythm too. ;) Meanwhile, for other songs on which I am trying to hammer down the rhythm, like Burnin for You, (BOC) I can mute rhythm and keep lead.
I hope I have this correct. If not, I trust you will let me know.
Thanks again for the advice and recommendations.
