Are you an iOS user? Then I know you didn't pay heed to my fourth method, did you?
That's why I have researched a lot to find a service similar to Shazam for iPhone. Guess what? I have got one "MusicID".
You can download their app from iTunes app store. But you have to pay about $3 to get your hands on the app. Though they have an Android app, Shazam is much better according to me.
After the app installation, you can play the video near your iPhone to identify it.
In all the cases, you will find a solution using any of the six
methods given above. Still, I have two bonus methods for you that
include no installations.
