Culture difference?

We chose an overnight travel back from Bamenda to Douala. We thought that we were lucky as the bus left on time (10:30pm). At that moment I was already very sleepy ( I normally sleep before 10pm in Kumbo), the music in the bus was loud and I thought that it would stop soon (as from my experience last time, the bus driver turned off the music when it started to leave). I kept waken up because of the music several times since then. At around 1pm, I was sort of mad and I shouted to the bus driver, 'Could you stop the music please?' (There was no way for me to walk to the driver seat and talk to him as the bus was moving down in a very fast speed T_T). One of the ladies in the bus laughed and said 'You know what...hahaha....The white man wants to stop the music hahaha...Here is Cameroon..hahaha'...and a series of words which I don't understand) in an annoying voice. Afterwards, the bus driver turned the music even louder. Ok, maybe it's a culture difference that they listen to African pop music at night while sleeping??? However, some more people tried to say 'turn it off' during the journey.
At around 2pm, the bus stopped for a while so that people can get out for food or something. I asked one guy sitting next to us if it's normal for the bus driver to turn on the music in such a horribly loud sound at night and he said that it's not normal though it could happen. I asked if he enjoyed the music and he replied that he could only enjoy it during the day. Another guy sitting in front of me told me that he asked the bus driver to lower down the music but he rejected as there was only one volume for the music. Jeff was angry and he tried to talk to the bus driver again. The bus driver laughed at him and walked away. Jeff followed him and said that there were babies in the bus and how could he turned on the music so loud but the bus driver kept walked away.
The journey continued and the lady who laughed at me kept talking in a very loud voice about me asking the bus driver to stop the music. Another black man got angry and walked to her to ask her stop talking. The lady shouted back, ' You are not Cameroonian!' Luckily they didn't fight and the lady stopped talking finally.
The music kept playing for the whole journey!!

It was a horrible 7-hour journey to me!!!
