If it's the extension, then unfortunately it isn't feasible for this addon to work on it for now.

There's a cap on these ID things, as the service isn't really even free. If you're a hardcore user, I recommend making your own account at acrcloud.com. You get 100 id's for free every day on the 'free plan', which starts after the trial plan ends.

Check the preferences page.

Thanks for letting me know this happened. I'll see if there's something I can do.

edit: thanks for updating, and thanks for the extra feedback. I'll make sure to include information about the free plan/trial somewhere as well, based on this.

Yeah, I made this so people could find that one odd song out there - every once in a while. Not really every song in their library. You can make your own account at acrcloud.com and get 100 free ID's every day, just for yourself. Check out the preferences page.

I'mma contact acrcloud (when I have time) and see if there's something they can do here, but I really suggest you make your own accounts if you have a big backlog of things to ID. Or use shazam like you suggested yourself.

There's actually no way of "buying" this addon, it's just the message the server gives off. I'll change that sometime.

Sorry for the misguided hopes, and thanks for letting me know this happened.
