In a few hours Sirius XM will begin an on-the-air memorial. That's nice.
Sirius XM has been running promos for the memorial, describing Lynn as "unique and one of a kind." That's not nice. In fact it's redundant and STOOPID.
"Unique" means "one of a kind." There is no need to say both.
"Unique" is one of the most abused (that's worse than merely misused) words in the English language.
It's very common to read and hear the phrase "most unique." It's used in speeches, ads, commercials, websites, books and news reports. It's used by idiots, and by smart people who should know better.
