In this case also just their interesting approach to privacy. I'm not telling a random internet service for no reason my proper first name, my age or my gender. I can see that there's maybe a reason for age and gender when suggesting music (even though it should be optional nonetheless), but my first name? Are you going to suggest me songs where people chant my name or something? And because they insist on this ridiculous requirement of entering my first name, it also just becomes much less credible that they actually need my age and gender, and are not just collecting that to sell it away.
