Before I worked in film, I worked as a designer. I was the last generation of designers who went to a four year college, learned art history, and were taught to actually use some problem solving and creative combo to cook up designs.
These days, designers are pumped out by certification academies that assume if they can teach you photoshop, you're a designer. I certainly would look to other designs for inspiration and ideas-- and even totally ripped stuff off if I really loved it-- but generally I followed the rule of 2. If you copy the font and the color scheme, have your own layout and elements. If you copy the layout and color, don't use the same fonts. Generally, working with your own assets you'd end up doing something original, or let it lead you to something new.
That's not how the younger generation of designers see it. Not ALL of them mind you-- but the ones who coast certainly do. My GF is an illustrator who is ripped off constantly to the point of having an IP lawyer on retainer. I really don't want to be a "kids today" person, but the generation raised on the internet think that if something is online, it's fair use to copy/resell/bootleg/whatever.
And just to play devil's advocate-- I know people who have worked at BLT. Like most ad agencies that work in media, they work people to the bone. This could have been the result of an entire team of junior designers pitching ideas for days, and at 3AM the day before they had to pitch to the art director, when they were exhausted, burnt out, fearing for their job, and still one comp short to pitch-- maybe they looked at a CD on their desk and said-- I'll just copy that to fill things out.
And oops-- it got picked.
Odds are though, it was a lazy art director who gave the CDs to a JR designer and said "make it like this, no one will know or care." SURELY THERE'S NO OVERLAP BETWEEN STAR WARS AND VINTAGE AFRICAN AMERICAN MUSIC!
