Since i'm involved in this process to a degree, i've been reading more about it.
The `facts` i seem to be reading are this: A&R , Publishers etc....hear a lot of well recorded stuff on a daily basis....and your `good enough` version might just not get their attention...it might even not get played.
But, if your a good songwriter and your work is of `hit` quality,even though it might be a little rough, it still might get a chance somewhere within the industry...
The better quality demos ,say something about the creator of the work,that their committed , they take their work seriously..this sits well with men in suits.
I' m sure there's loads more points...like getting your hands on 'tip` sheets..... .....in truth , even with talent.it might be the case that money needs to be spent..somewhere along the line?
