AC/DC - Back In Black
Funny thing is that when this album came out, I was determined not to like it. I was a huge AC/DC fan and a huge Bon Scott fan. This album was released just a few months after Bon died and I was appalled that they could replace him so fast. It seemed cold. So, I wasn't going to like it. After a few months of everyone around me listening to it, I finally caved and admitted that I loved it.
I have no proof but I think Bon had to have written
You Shook Me All Night Long (or at least a few lines of it). There are some lines in that song that are pure Bon. AC/DC had to have some of this album written when Bon died to have released it so quickly.
Edit for additional info - Bon died in February 1980 and this album was released in July 1980.
