Kidding 
without music ppl think they gona die. Once me and my friends were coming from ANSOO lake and it was around 9pm. we were told that now its almost impossible to find any jeep around here, but luckily we found one. on the way back, all friends said "Tape on karo". when we get closer to "Glacier" the driver stopped the jeep, stopped the tape, and recited Kalima. when started jeep, all said "Tape on karo". Driver said " O bhai, hamain nai pata yahan say sahi guzartay hain ya nai, hum TAPE on nai karay ga"
and then when my friends (i came here before so i knew that its gona be dangerous at that time, but they did not know) saw glacier in jeep light, all of sudden i could hear breaths as well, and Allah Allah kar kay glacier cross kiya aur ja kar phir khoob bisti ki kay ganay lazmi nai her jagah.
