Goodluck but the music startup scene is saturated with heavily funded projects as it is set to be a $100 billion dollar industry by 2016. So I'd suggest you focus on local content aswell as Africa maybe?..Only then will you be able to gain traction I think.
I also checked out the site. You're gonna need to partner with a talented HTML/CSS designer as right now the site looks kinda boring but I guess thats part of the reason your trying to raise the funds
