Song parodies, mash-ups, etc.

Tim Hawkins Aging Rockers (in case it gets taken down)

Probably been posted many, many times over, yet somehow, I still get a good laugh out of re-watching it, every now and then, maybe even more, by browsing through the comment section, reading upon all the angry Slipknot fans. It was Basshunter and Boten Anna, mixed with the American act, and yeah, sadly its gone now.
But the again, I have not seen it or looked for it, for some time. Kind of sad, as it was hilarious to behold, specially the anger it seemed to bring with it.

I think it also got a few similar themed video/mash-ups, where other dance/trance tunes, got mixed together with Black Metal video clips, and again, most of the fun, was reading all the sewage coming from the Black Metal fans, who surely did not find it as funny.

Anyway, some parodies/tributes is actually so good, that I actually love them more, than the original one.

I think I only have heard or seen the videos of Eat It, which got lots of airtime in my country, even as far as into the mid 90s. Where as most of the others, I guess I was just too young to remember, or even understand that they were in fact, mostly parodies of other songs.
Not sure of how many of the songs you posted above, which are covers/parodies, or is actually originals, written by Yankovic, but he sure made quite a career on handing out funny and very catchy music. Have not been too updated on what he has been doing lately, and I guess the last time I remember one of his parody hits, was way back in the mid or late 00s, when he did his version of a rap or hip-hop song, that I do not remember the name of.

Anyway, for my part, the first one that comes to mind, is the hilarious and very memorable opening title track of the funny Leslie Nielsen comedy, Spy Hard (1996), which I saw several times on cinema back in summer of that year, and the opening song, and the shot of the camera going all the way up the nose of Yankovic, got some great laughs, every time I saw it, from the audience. In fact, the opening song, got probably the best laughs, throughout the entire film.

Thanks for your picks of the many Weird Al Yankovic songs. 

While most likely unkown to the rest of the world, so to speak, at least this norwegian mockumentary musical project by Espen Eckbo, named Boyzvoice, which surely were a parody of the still very much on going boy band craze during the late 90s and early 00s, which also was followed with a movie called:  Get Ready to Be Boyzvoiced (2000), that were like a This is Spinal Tap!, for the boy band era, and worked very well at that.

Anyway, the first time I noticed Boyzvoice, were during the latter part of 1999, with their hilarious christmas themed hit (it became very popular, so much, that many actually bought into, thinking they were a real act, and not a parody). And the best part, is that Eckbo took the christmas theme, and continue on with his own take on the Big Brother reality show, with Nissene på låven (2001) or Santa's inside the barn, that surely is among the most funny and enjoyable christmas themed tv shows, ever made.

Well, enough of that. Here is a few of the "classic" Boyzvoice releases of the late 90s and early 00s:

Let Me Be Your Father X-Mas (1999)

12 Year Old Woman (2000)

We Are the Playmomen (2000)

Older parodies of music was usually supplied by Spike Jones and his City Slicker
