If your wife likes Metric, have her listen to this tune by the Framework. Another Toronto Indie band in the same vein.

I think this is their most popular song. 

I played this over the Bluetooth speaker and my wife stopped what she was doing and just looked at me and said "I can't believe you're playing this song". Apparently it's been a favourite of hers for ages and I've never heard it 🤣🤣
