As a listener, and as a broadcaster, I've always preferred (what I consider to be) a balancing of the elements.
No long commerical breaks...I don't like to have more than three commercials in a break. And, I like to have something quick between the second and third commericial: promo something that's upcoming, whether it's somthing that ahead within a few minutes or a few hours...
No long breaks with too many elements (promos, commercials, bits, etcetera)...
And try to play two or three songs before stopping for an exented period of time ("break").
I have no problem with the "song, commercial, song, commercial & programming element, song, commercial" format...it just needs to be properly, and comfortably, executed.
Being a fan of radio is what made me want to work in radio...these are the things that seemed to be great and attractive formatics and procedures.

"...25% of all women who listen to the demographic’s core adult contemporary or CHR stations feel that the stations do not understand them..."
