Yes, the flaws or mistakes in songs or in voices were often what made them so wonderful and what drew you in. It gave the songs something human and unexpected and made them feel so alive. Basically as music has collided and mixed with technology over the years it has altered the course of both what we hear and what is popular. 

I disagree with people that say there will never be another great rock 'n' roll band. I think there could be but it all comes down to how they find their sound and how they create their songs. Listening to an interesting discussion recently about how Jimmy Page found his guitar sounds was pretty fascinating. He searched for sounds for each song and the way he did it was not at all how a guitar player today would likely attempt to find a sound or sounds for a song. 

I still love music but I mostly look back for it rather than to current music. I don't want to say there is no good music being made now, there likely is I just don't know where to find it and so remain unaware of it. 

I still want to hear guitars being played, keyboards, sax drums. Basically, I still love to hear instruments and players. Sitting in a room hearing people play still remains one of the great joys of life to me. It doesn't matter if I am listening to Tommy Emmanuel play something mindblowing on guitar, Brad Mehldau hypnotize me on piano, or my goddaughter playing cello in her living room. Music has an effect on me. 

I'd be happy singing Danny Boy with Mick as we stumbled drunk into the night from a pub in the shire. It would be a musical event...while people screamed at us to shut it. Like to see the judges on TV rate that.
