Most likely this is an even lazier attempt at confusing listeners than soundalikes:
These remakes aren’t motivated by artistry, but by money. Soundalikes
are a completely mercenary venture. The whole goal is to duplicate the
original song in every respect, using studio musicians and vocalists,
in an effort to lure consumers on digital music services ...
Deezer.com lists Morricone as composer for the Ave Maria Guarani. Given how popular the text is, I don't consider the exclusion method as reliable, so without having listened to it, this seems most probable answer by far.
Since Deutsche Grammophon has a CD recording attributing it to Morricone and he seems to conduct it personally here in the Shazam video, ...
I believe that would be: Rage, by Moxix
The lyrics are dialog from a character in the game, RAGE.
“Ah, you're awake. Good. I like my prey to know what's coming. I promise, this will hurt!” - Ghost executioner
Bebs has already got the ident nailed, but I thought I'd add a little more info...
The picture is post-Woodstock, btw.
1970 - after Tyrannosaurus Rex but before the full-blown glam of T.Rex. The picture was originally in colour & was used as the album cover for the first album after the name change - T.Rex
The spanish flamenco part was not composed by Queen, but improvised by an external musician, Steve Howe, invited for this song.
Wikipedia article about the song (according to Prog Magazine) says:
Inside, there’s Freddie, Brian and Roger all sitting together. They go: ‘Let’s play you the album’. Of course, I’m hearing it for the first time […] And they ...
His work Capable has the song Baila Mi Cumbia from the Youtube Audio Library Music (YALM).
Translated from French, it says:
You are free to use this track on anyone of your videos.
Any artist using one of the YALM song is allowed to not quote youtube and therefore can have all the rights of the video. There are thousands of youtube videos released every ...
It seems it might have been Franco Ricciardi, playing two roles (Arturo and Normanno).
In the MYTO 2009 album release back cover it seems to appear his name:
Another reference can be found in esdf-opera.de.
This transcription of a George Harrison interview in 1969 says that John Lennon played it:
John plays lead guitar and sings the same as he plays. And, uh...this is good because it has, um - it's really basically a bit like a blues. The riff that he sings and plays is really a very basic blues-type thing. But again, it's very original sort of John-type ...
A quick Google for "blonde female guitarist" revealed her to be called "Orianthi Panagaris". She is a very big deal indeed, having been hand-picked by Michael Jackson for the ill-fated "This Is It" concerts, and therefore likely appears in the rehearsal film that was commercially released.
I'm not sure how accurate the liner notes to George Michael albums are, but the only credited bassist on the studio album that contains "Cowboys And Angels", Listen Without Prejudice Vol. 1, is Deon Estus. It appears that Estus had been playing bass for Michael since his days with Wham!, and Michael even helped produce Estus's solo album, Spell, which was ...
The song is "The Great Gig in the Sky" by Pink Floyd, from the 1973 album Dark Side of the Moon. I imagine that album was very influential in Curon's life (as that album and Pink Floyd is for many who grew up in the 1970's). I think there's a connection with that song personally for Curon, and it also is connected with the airplane symbolism in the movie ...
There is nothing to stop people from uploading garbage to sites like YouTube or Soundcloud. There are whole channels of algorithmically generated content. The only quality control is the voting system.
The only major problem here would be if he is stealing other people's copyright content. But that's something the copyright owners have to control themselves....
Wikipedia has it as composed by George Michael and his musical partner in Wham! Andrew Ridgeley, although in some places (Japan, Canada and the United States) it is only credited to George Michael.
This is confirmed by the back sleeve of the single:
They did not perform together. According to this interview, they played on 2 separate tracks.
On your first solo album (1970) you pulled off a coup getting Clapton and Jim Hendrix to play on Go Back Home and Old Times, Good
In California we had that jazz theme where everyone could be on anyone

The picture on the linked cover is of Richard Chamberlain & Rachel Ward, who starred in the TV series.
The song is, as you said, Henri Mancini, sung by his daughter, Monica.
[In]famously, the Varèse Sarabande version of the soundtrack was re-mixed from the original sessions… & someone seems to have forgotten to include the heavily-featured dulcimer ...

I personally do not know this track, however, I used SoundHound to id it and it's given me "Wait For Me" by Giraffe Squad. I've listened to your clip and the SoundHound track. Pretty sure that it is this track.
From the video's comments, in Portuguese:
A co-autora e vocalista desta música é a carioca Valéria dos Santos

The co-author and singer of this song is Valéria dos Santos Costa from Rio de Janeiro who recorded with the French musician Manu Chao ...
Beatles' member George Harrison famously said something similar when complaining about modern music (the below quote specifically referred to the Spice Girls):
The good thing about them is that you can look at them with the sound turned down.
On a long shot, Pat Benatar, but rather brief signature to fit in the space.
Google search brought back these : Crimes of Passion. Get Nervous.
Because of the nature of the question, links to back up the answer are bound to be from sites where albums or other merchandise is for sale.
I don't know the top example, but the bottom example is the very famous quartet ("Bella figlia dell'amore") from the third act of Verdi's opera Rigoletto.
This particular performance is a rather...busty one by Pavarotti and Isola Jones. You can enjoy it here.
This is identified at the same link you provided as:
"Te Quiero a Ti" by the California Brass
Although it's pretty clearly the same song (that dissonant opening riff on the horn is pretty distinctive), it seems that they changed the title and the lyrics for the Spanish version --which is not unusual.
It's worth noting that the playlist is listed in full ...
