Go to the Add-On Options for the Song Identifier. There's a tutorial on how to set this up. It figured out the song within a second. All the 1-stars don't know how to read.

Did not work for a single time. From the very first attempt it was showing message 'daily quota limit exceeded'.

Works great. Better than shazam, dare I say. The access key thing is slightly tricky to set up but if you even slightly know what you're doing you'll be able to get it done in like 8 minutes.
The automatic Soundcloud lookup link is very much appreciated.
Great extension :)

first time use: limit for today exceeded. OK BYE

If you are competent enough to follow some simple instructions and set up your own account on acrcloud, then it works perfectly. The negative reviews are from people who did not understand this.

Not finding songs. Bad extension. Don't download this.

Barely identifies most songs and says I've hit a limit on use. It's only worked like twice.

Used to be great. Now it's begging for me to sign up so it can sell my information. Great. Greedy devs strike once again.

useless, also got banned on acrcloude

Found correctly few songs, event a not popular one

You CAN NOT have a worse extention than this.

AHA Music is way more better and free, sadly its not release on firefox, only for chrome

dAiLy LiMit, daiLy LimIT, DailideezNOT identifier any sound 💀💀💀

Obviously this add-on was great when there weren't as many people using it. It uses some freemium service that can sample audio from almost any website, but has limited uses so the more people that use it the worse it gets. When it works it's great, but lately there's maybe a 1 in 3 chance that it doesn't come up with "Default account limit exceeded" error.
