Greatest app ever!

I spent a lot of time searching for an application like this, specially working in background so I can listen my music from my favorite apps.
I really dont understand the bad reviews, it does what it says, it lets you test before buying!.. so people dont test? Anyway, I prefer a lower quality than nothing or spending a lot to replace or add extra gadgets that you need to recharge, connect separately, etc... aggghhhh!
Thanks for this app! I am using it every day!
