At SpareMusic, we like to keep you up to date on what's happening with your release! Your release will go through multiple statuses before it arrives in stores. One of those is the In Delivery Queueue state.
This means we've reviewed your release, any metadata errors have been corrected and it's ready to go to stores. All that's waiting is for it to get to the front of the queue and for us to send the files to stores. This is what can take a little while at times!
We process hundreds of releases every day so at times the queue can be pretty long! Have no fear, releases generally don't stay in the state for longer than a few hours! There's nothing to worry about.
