The question of music has been discussed in this column earlier in some detail; please refer to it. I will, however, provide a brief answer to your specific question.

Many of the scholars of Islam, both ancient and modern, consider all forms of musical instruments except duff (tambourines) as forbidden; but, there are other scholars, who consider music and musical instruments as forbidden only if and when they are used for themes or messages that are declared as forbidden or undesirable. Based on the second view, as long as you stay clear off undesirable themes, and messages, then what you are doing can be considered as permissible. You must, however, remember that this permission is conditional on the fact that you are resorting to music as an occasional outlet only; for there is no doubt whatsoever that if your indulgence in music in any way interferes with your performance of your worship or other obligatory duties, then it shall be considered as strictly forbidden.

So, use it only as an occasional outlet. The Prophet, peace be upon him, has permitted us to have occasional outlets in order to help us to recuperate and refresh ourselves. Resorting to such occasional outlets may in fact be beneficial for our enhanced productivity/creativity. May Allah help us to maintain proper balance in our life, avoiding all forms of extremes—Aameen.
