Well, let me give you my honest comment and please don't get offended by my comment as it's entirely mine and I don't want anyone to take it personally. May be It's just me who feel this way.
I feel so called "Lok Music" extremely annoying high pitched noise pollution. It's not just above songs you listed but almost all the songs. I feel like I am gonna vomit when I hear those songs. Frankly saying I can't listen even 5 seconds of those songs. For me it's not even a song. I, including many of my friends, do not say this experience to those who listen to "Lok geet" because we don't want to hurt you and we don't want to unfriend with you. That's why I normally don't comment on these songs. I am not sure how many people in this sajha feel the same way as I do. As of your video, I don't have any comment because you are commenting on those videos which I couldn't listen or absolutely no meaning to me. I am not trying to insult you or your feeling but this is how I feel. I have listened many songs Rock, jazz, blue, R&B, Nepalese all kinds of songs, classical, hindi japanese, mexican etc. but I never heard worst songs than these high pitched nepalese folk songs. When I was in Nepal  I used to travel with Bikram Tampoo and buses and I had to listen these songs few times and every time I used to take pain reliever for my headache.
