Permissibility of Music in Islam

I was recently very much inspired by the emergence of music artistes such as Sami Yusuf and Maher Zain who I felt are doing a great job in spreading the message of Islam with modern music culture. Then again a long lasting anonymousness was striking my head, of whether music is permissible in Islam. From my childhood I have heard of repeated sayings from different scholars that music is haraam (not permissible) without a second thought. I have been trying to keep myself attached to those teachings, yet on many occasions human nature or Satan leads me to listen some sort of music. But after listening to their songs and their personal intentions I felt there must be some sort of permission and limit in Islam in terms of music. Alhamdulillah I came across this nice explanation which I believe will try to adhere to:
