Opinions are like pot holes. Every street has one.....or something like that.
Personally, I look forward to all musical submissions and many have motivated me to learn the songs which I have since added to my performing repertoire. I think the first was "The Nearness of You". Several here submitted their renditions. All had positive points. I worked up my version and use it fairly often on gigs. There have been submissions of songs I already do and I may like the style they used better than mine, or the tempo, pads, or style edits, etc.
There have been many other submissions that I have worked on. The latest came from Donny's posting of "Driving My Life Away". I loved it. Okay, so it wasn't a SZ member but a demonstration of good use of the Genos. It grabbed me. The chords are simple enough, but I am still struggling with the fast paced lyrics....it WILL eventually end up in my play list.
As for recording myself....I tried it years ago and found it to be a hassle, too time consuming and I was my own worst critic. I'm happy to play for and with anyone here that wants to sponsor a jam like the ones Gary's and DonM had. I learned a lot there and made some long term friends in the process. I don't know if any of my material would have passed SZ critics, but no one threw anything at me.
