Yes, I can relate to that. It comes under the category of invasive thoughts which will not leave you alone. Mine start out being energizing and intriguing but end up tedious and tormenting. My latest one is music of Ian Dury and the Blockheads. The lyrics are so brilliant.
For me it seems to be a typical bipolar characteristic. It has served me well in the past as it related to study/work because it led to intense focus.
I guess if it is interfering with your functioning, you will have to ask for help with it. In some ways I would rather be like that than someone who is not interested in anything.
