Such a fuss is made about tongues (different languages) by the Pentecostal/Charismatic, yet. Paul states, they are for the "unbelievers." Besides that, there were guidelines set down when tongues were active. Such as: 1 Corinthians 14:27 "If any man speak in an unknown tongue, let it be by two, or at the most by three, and that by course; and let one interpret. Do the Pentecostals abide by those rules? All we hear today is a bunch of gibberish, not other languages.
They call themselves Pentecostals. Well, the tongues of Pentecost were not even babble, rather real, known languages, the miracle they were being spoken to foreigners standing around by Galilaeans who did not know the native languages of those foreigners, and speaking of things they understood, of the wonderful works of God, in their native tongues:
Acts 2
4 And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.
5 And there were dwelling at Jerusalem Jews, devout men, out of every nation under heaven.
6 Now when this was noised abroad, the multitude came together, and were confounded, because that every man heard them speak in his own language.
7 And they were all amazed and marvelled, saying one to another, Behold, are not all these which speak Galilaeans?
8 And how hear we every man in our own tongue, wherein we were born?
9 Parthians, and Medes, and Elamites, and the dwellers in Mesopotamia, and in Judaea, and Cappadocia, in Pontus, and Asia,
10 Phrygia, and Pamphylia, in Egypt, and in the parts of Libya about Cyrene, and strangers of Rome, Jews and proselytes,
11 Cretes and Arabians, we do hear them speak in our tongues the wonderful works of God.
12 And they were all amazed, and were in doubt, saying one to another, What meaneth this?
No phony babbling, that sounds like you'd have to conclude infants in diapers are filled with the Spirit, until, what, they're backslidden enough to learn intelligible speech? And it would never occur to these people that you can stick a parrot in a room, keep saying, "Polly want a cracker?", and the parrot will, eventually, be, likewise, saying, "Polly want a cracker." It's not the Holy Spirit come over the parrot.
There's a classic book about the history of the delusions of crowds and its madness. You get some emotional hysteria going in the room, and it's monkey see, monkey do, proven by the absurdities of "holy laughter" and dog barking, the whole room worked into a frenzy of behavior that's sheer stupidity, beyond comprehension of being even the behavior of any intelligent human being, and claiming it's the Spirit, but the whole room going at it, in what amounts to a shameful and embarrassing spectacle of nothing more than disorderly behavior, void of anything spiritual. As you point out, there are recordings of it all on YouTube, just ghastly stuff of no spiritual edification, rather even bringing the faith into ridicule, proof to the everybody in the world, of half a brain, that Christians are idiots and crazy. It doesn't even take spiritual discernment to see the phoniness of it all. And it has nothing to do with Christianity.
