I do have the family plan actually, I forgot about that!
And I do occasionally. Certain live albums and more niche stuff can be hard to find, and one hit wonders can be tricky depending on the genre and time the song is from. The song I’m Blue by Eiffel 65 is only available in a longer club mix and not the radio edit, for example.
I will say that, in my experience, it has a slightly larger selection than Spotify for classic stuff and different versions of the same song (covers, remakes, remixes, etc). For example, my husband was very excited that they had the whole readout of How the Grinch Stole Christmas by Boris Karloff (in two parts, but still) because they used to play it on certain radio stations every year around Christmas. On Spotify I was only ever able to find the same version of the song from several different albums of Christmas mixes.
Two or three years, I think. So far the price has stayed exactly the same, they still have no ads, and they haven’t made any changes to the app to try to advertise features or anything like that. It was (and still is) a nice change from Spotify, Apple Music, and even YouTube to be honest.
