I like the youtube video. I dont think the website looks dated, it is just minimal.

One thing I think you should focus on is getting Artists on there supporting you. You wont get any subscribers until you get the artists. Once you've got the artists producing media - you can use their fan base to grow membership.

I would never subscribe to this service unless there was an artist I cared about using it. I would suggest a strong marketing campaign focussed on winning some Artists. I have known bands with tiny but dedicated followings - those are your paying subscribers.

Best of luck!
