Anyone using Airbit or other media player on their own site?

[Straight2Vinyl]

Hey people, I'm going to build a site for all my music soon. My own titles for sale plus beat and music licensing. I'm just curious what media player to use and more importantly, for me at the moment, will I need hosting with a lot of storage for the files or do these 'beatstore' media players like Airbit, Soundgine and Beatstars keep all the files on their own servers thereby greatly reducing the use of my sites own store/resources?
I'd appreciate any help I could get with this. I built a site before, but it was for my personal training days and the requirements are going to be very different this time around.
Cheers.
