I first of all welcome you to this great community which shows any body who is interested in Islam,the true Islamic teachings.MashAllah(Praise be to Allah) you are only 16 and want to look into islam i think thats amazing.
The reason you feel good when you listen to quran is because Quran is the Last and Final message of God after Torah(Gospel) and Injeel(Bible) and its in orignal text Arabic which has been preserved by Allah(s.w.t) from the day it was revealed to Muhammed(P.B.U.H), not it even a letter is pullouted or fabricated.There are millions of people around the world who has memorised the entire quran letter to letter,cover to cover.
There is no mistake or harm in reading and listening to quran.infact every muslim reads and listen to quran its is one of the prefered things to do. Islamic Songs(nasheeds) are also fine if they dont have any sort of music in it.
Sister i recommend you to read the entire quran in your language and InshAllah(god willing) the creator of you and me will guide you to the straught path, the path of Ibrahim,Moses,Jesus and Muhammed May peace and mercy of Allah be upon them all
