I received a trial of Sirius when I bought my vehicle. My Dad bought a life-time subscription (at a time they were practically giving them away) so I had listened to Sirius a few times when borrowing his car. My impression was they have bought and paid for a particular catalogue of music and they play that catalogue pretty exclusively. That catalogue seemed to have the 4th or 5th most popular songs from a huge list of artists but rarely the top 3. It is a massive catalogue but when you listen to it enough it starts to become repetitive and I would start to wonder "do they even have any other songs by that artists" after hearing a b-side for the third or fourth time.

I even considered buying it anyway since I like to go on trips to remote areas (fishing/camping) and can't rely on data for my phone for Spotify. In many rural places there is only a single radio station and even then it may be mostly static. But I found in those locations even Satellite reception was spotty, especially in the mountains or valleys I frequented.

Compared to top-40 FM radio, Sirius is amazing. It had its time. But comparing it to the internet with Youtube and Spotify (or Apple Music, etc.) just blows it away.
