I'm looking for a site to which I can upload an audio file and identify what music is playing in it.
Kinda like Shazam, but without the need to have a smartphone, and without listening through microphone.
I'm planning on using it on Windows and mobile devices which do not support the actual Shazam app because they're too old. It doesn't have to have a Windows native version, but it has to work at least on Windows in a browser.
Before posting an answer, please check that what you found works, because there are some sites out there which are still online but say their servers are "on maintenance" or "can't be found".
