On the other hand a reworking of a famous song might produce a radio-friendly track and give him attention from other circles.
i dont know where you live or how old and out of touch you are but what radio. radios dead as network tv. if he wanted to make a "radio friendly song" to get attention hed collaborate with ryan adams whos a giant fan etc or get a known producer to co write some electro pop song but he doesnt because as much as he likes chart positions its not his top priority. you sound like popul;ar success is the only way you will accept that anything is worthwhile. also its funny you mention novels after your praising of fight club which was only so so it quality. good idea, relevant topic, so so execution
