Sound Search Playlist in Google Music

Google's Sound Search widget for Android has a history page which shows all the songs that have been recognized by the application. You can also find this list inside Google Play Music if you go to this playlist. This is especially useful if you subscribe to the All Access feature and you can play all the songs.

A Google screenshot shows the Sound Search playlist in the sidebar:

"Hear a song you like while you're out and about? Touch the microphone on the home screen of your Android phone or tablet. Google Play identifies the song and adds it to the Song Match playlist. You can also use the Sound Search for Google Play app," mentions the page.

The first feature doesn't work for me, but maybe it will be added in the future.
