Years ago, my brother-in-law observed how an Arranger Keyboard is used... and he proclaimed to me... isn't that cheating? I replied, "Frank Sinatra does not play all those instruments... nor does he lead the band." The idea, as presented earlier, is to create the best product possible by using the tools available... legally. Some would say that having a multi-track recorder... so you could use or eliminate certain tracks... is not "Kosher!"

To your point, FD... if I had all the resources available to me that money could buy... and had the money to acquire those professional resources, if I believed enough in the song, I would do it. I know that is an over-simplification but we are trying to convince each other if using BIAB and other, similar products is good or bad. I think the method is eventually insignificant if the final result is memorable, lasting and leads to a song that generates income sufficient to recoup the proceeds that went into it's production and promotion. (I don't claim to know diddly about promotion but understand it takes influence, power and enormous sums of cash.)

Remember Tiny Tim and his ridiculous Uke? Then there was "Pants On the Ground"... "One Note Samba".... the list is endless. Some required massive backing, some... not so much. Most eventually faded into the history of music.
Those that survive for decades, even centuries... are the benchmark I compare the songs or compositions I hear at JPF (or other sites) from time to time. We are lucky to have a few people here with that ability to eventually succeed.

Have a great weekend. ----Dave
