I didnt know some of them were covers especially Tainted Love, i know Marylin Manson covered it recently but didnt know it was a song from the 60s. Totally agree with Number 2 Pet Shop Boys did i great job!
The Bates - Billie Jean
Cake - I Will Survive
Mott The Hoople - All The Young Dudes (stretch the point)
Muse - Feeling Good
Eric Clapton - Knocking On Heaven's Door
The Donnas - Wig Wam Bam
Roger Taylor - Racing In The Street
Marvin Gaye - Heard It Through The Grapevine (long after Gladys Knight, but so much better)
All superb, none on that list.
Although of course the Boys do lose some points for their cover of "Always On My Mind" due to it bizarrely keeping "Fairytale of New York" from being the 1987 Christmas No. 1!
