Hey! Thanks for stopping by. I'm glad you're enjoying the music. SOS is a distress code. It comes from Morse code where S is three short flashes and O is three long flashes. Though if you can't remember that, three blasts of a whistle, shots of a gun or flashes of a light, and a pause then repeat is probably going to attract attention.
I think the three songs you picked will have the longest shelf-life. I predict the other's will become dated soon enough - except for young teens where such songs mark their passage out of childhood.
I like the song you posted; I didn't know that much about Mirbek Atabekov but his is great in his own right!
