Some really good suggestions here for me as beginner. I'm playing along with tracks that I like & are manageable for me. What I try to do is add stuff I wouldn't normally listen to so I'm less familiar with the song so I have to listen a lot more.
I use Scott's lessons as well but at the moment I'm doing more of the playing along. Listening to a band last night has also given me new ideas for songs to practice so that was a useful, unexpected visit to the pub!
I do think the 15 minute scheduled practice would work well for me, big thanks for that.
