MAB,
I couldn't agree more with you about your advise to play songs out and get a feel for the audience's reaction before anyone spends money on a professional recording. I realize not everyone (especially a new espiring songwriter or artist can afford to professionaly demo every song they may write). It's truly best to pick and choose the best songs to spend money on.
However; I would also suggest that anyone wanting to share a song; whether on a songwriting site or take to Nashville for a workshop that a professional may hear, to have an excellent recording whether from a local studio with local musicians or preferrably a Nashville recording with professional studio musicians.
I personally prefer my songs to be demoed by professional Nashville musicians; but I also prefer gorgeous blondes.
However; I can't afford both. Ha!!!
