Maybe I'm contradicting myself in what I said in my last post in the To Post Or Not To Post Thread - that starting non-ABBA music topics here is a waste of time. Hope not in this instance, so here goes!
Anyone on this forum who is into other styles of popular music in addition to ABBA, might want to check out Rick Beato on YouTube. I think he has some very interesting things to say about about some pop and rock musicians and their music - not ABBA as of yet, unfortunately, but hopefully he will sometime - and also classical now and then. Rick Beato is a trained musician and knows his stuff, and is also a very good guitarist, by which means he often demonstrates his points. However, in this video, he's talking about Beethoven and his deafness. Well worth watching, imo, even if - perhaps especially if! - you don't go much on classical music :-)
