Most of it sounds like we do more than we do, but all of it is necessary up front for the things we enable after you connect. I can assure you that we don't do anything that isn't about making your music experience better.
I understand the hesitation, we try to avoid asking for anything that we don't need to make the user experience better. We don't post anything without you explicitly performing a "share to facebook" action, so you can rest easy on that front. And we ask for your profile info so that we can see what bands you already like.
