I ordered my Google Nexus 7 in September, 2012, so I've had it for a while. I was just thinking recently that this baby can probably do a lot more than what I do on it.So, in my quest to see just what it can do, I found a Youtube Video showing how to use the "What's This Song" app which I had seen pop up on occasion on my Nexus 7.
To test it out, I clicked on a music video on my Mac. As soon as the song started to play, I clicked on the "What's This Song" app. Within seconds it came up with the song, artist, and Google Play price.
FYI: "Blessings" by Laura Story is $1.29. What a beautiful song.
If you don't have this app on your Android device, I'd recommend it.
