I speak in so called "prayer language" Tongues, I also sing in it. I beleive that anyone who has been baptised by the Holy Spirit can obtain this, as its more of a personal relationship deal going on. I did not think I had been baptised by Holy Spirit and therefore I never even considered I had this gift.
It was not until we had a seminar, quite a few years ago now, where we were taught about gifts of the Holy SPirit and if you are a genuine beleiver and follower of Christ but have not been baptised by Holy Spirit yet, then there must be a reason why. Went through all the blockages that prevents this from happening, ties not severed through involvement in cults or activities such as mediumship, Soul ties and so on.
I went throught all this, but still nothing, so at end of the 2 days stood up and went forward for prayer, again nothing happened, I thought, Meh oh well, then just as I was going to sit down the whole room went black and i was transported back to when I was a teenager and an event I had practically forgot.
It was at our church weekend holiday, had communion for first time, a wave of light came over me, everything seemed bright and I felt amazing, strange tingling and goosebumps, then it went, now I remembred this and did not know what it was, I had not been taught anything like this at my Baptist church, I now knew this was my Baptism of the Holy Spirit. So all these decades I have been living with this, but never knew it, partly down to the church thinking that even raising a hand in worship is rebelious and dangerous.
Anyway I told the chap running the seminar, he asked if I had tried speaking in spirit, that is toungues, I replied I had not, so he said just give it ago, just start speaking in it he said, so I did, and it just flowed out, yes I was making the sounds, I was speaking in this language that only God knows, but I was not thinking about the sounds or what sounds to make as it came out, it just came out spontaneously.
He stood over me, listened and prayed, then said I had an unusual dialect and sound, but it was 100% from holy Spirit and was all good, as many people who speak this or try it can be influenced by demons and bad spirits.
Unfortunately, this amazing gift that everyone can have is met with suspicion and ridicule, just read the responses on this thread. It is also very much abused and many people who claim to speak this, are speaking it from demonic spirits, not Holy Spirit. All this is Satan at work to destroy as much as he can, if most Christians reject the gifts, then job done.
Despite all the clever arguments and reasoning which is worthy of the best lawyer in the land, people such as myself are living proof it is real. I know what I have and I know what its for, I do not abuse it or use it to show off or score points, that would be wrong. Just saying "Thank you Lord" in our own language is better than speaking an hour in tongues, it is great to speak in tongues if I do not know what to say or pray for but feel prompted to do it by Holy Spirit.
So well there you go, thats about it.
