Debbie, do you subscribe to Amazon Prime? If so, there are thousands of free songs you can listen to with your Dot and Bluetooth speaker. Just download the Amazon Music app and you can add playlists, songs and albums and stream them through your Dot. If you set up a free iHeart radio or Pandora account you can ask her to play radio stations or different types of music.
If you have a smartphone download and install the Alexa app and you can tell your Dot to add items to your shopping list and they will show up on you phone app. We add items whenever we think of them or run out of something. (My neighbor's kids add ice cream and candy to her shopping list when she's not around.

)
There are tons of things you can do with the Dot. They're on sale right now.
