Does Siri play more free music compared to Alexa?

Asked by mazingerz88 (29393) October 21st, 2022 from iPhone

I noticed that between my Alexa and a friend’s Siri device…Siri plays more selection of songs I like to listen to and for free. Alexa offers more songs but not for free. My friend is indisposed so I couldn’t ask if he pays Siri a fee for music service. Thank you.
