I bring this up because in another discussion (https://www.reddit.com/r/Music/comments/uzktg0/albums_that_marked_the_end_of_an_era/) online, there's an argument that suggests that Queen's 1991 album Innuendo (https://en.wikipedia.org/wiki/Innuendo_(album)) was not only the final Queen album to be released in Freddie Mercury's lifetime, but it in a sense, closed the doors on '80s music. That same year, the grunge revolution that was led by Nirvana and Pearl Jam would breakout into the mainstream and more or less, define the following decade in music.

Heart went from being Folk Music in the 1970's to being Corporate Glam Rock in the 1980's. They admitted they went Corporate Glam Rock in the 1980's because they wanted money. Let's face it, the 1970's Folk Music they did in the 1970's would NOT have been successful in the Corporate Glam Rock of the 1980's. They would have flopped big time if they stayed with the Folk , music. In the early 1990's before Grunge took over, they went fluffy Pop, once again because they wanted money. The Corporate Glam Rock of the 1980's would not have gone over well with the Fluffy Pop of the early 1990's. Heart adapted to whatever musical style was the trend of the time.
