How to figure out the name of the soundtrack being played in a video on YouTube.com and elsewhere?

Trying to figure out the name of the soundtrack being played in a video on YouTube.com and elsewhere with no lyrics especially?

Its quite easy using a Chrome browser extension called “AHA Music – Music Identifier”.

First visit the Chrome web store. Then install the extension. Then head over to YouTube or elsewhere and play the song under consideration in your browser. Wait for a few seconds for the tune to pickup a bit and then click the icon for the plugin on the top of the browser.
The extension will tell you the name of the song in a few seconds.

Another way is to use the Shazam app. Use your mobile phone to run the app and place the phone next to your computer’s speakers.
