The most obvious answer is Sweet Dreams. Credit to Scott Putesky (Daisy Berkowitz) for taking that song and remaking it into a classic goth anthem. RIP Scott. I try to always mention him, cause I never want him to be forgotten in time when it comes to Marilyn Manson's music.
Since his triumphant resurrection last year, I can proudly flaunt my Spooky Kid credentials. MM was a huge part of my teen years and I am so proud to see him clean, sober and performing at the highest level he has since 2000. His comeback has been so inspiring to me. It was like a childhood friend who you thought was lost forever suddenly returning out the blue.
Here is Manson singing Sweet Dreams, hitting screams he has not hit since 2000. This was a few weeks ago at a concert in Mexico that blew up and had over 200k people attending.
Some other covers I like better than the original.
Sexyback by Trevor Something. If you're part of my Patreon community, you know this is one of my favorite songs right now. I just used it in a video.
Little Wing by Stevie Ray Vaughan. A controversial pick here. The original is a certified classic and an argument can be made that SRV does not play it like Hendrix. But that's what I like about it. This is a case study of how masterful of a guitarist SRV was. It's not just a jam. He takes the song in his own direction and expands it.
I know Olivia Rodrigo did a duet cover version of "Uptown girl" with Billy Joel it was rather special for such a classic song hearing her sing about having a crush on a girl which sounds like a great story plot
If I had a $100 bill for every time you post stuff like this in this thread, I would be a rich man.
