As much as I like radarr, lidarr has some problems radarr doesn’t. Some bands nowadays do not release albums and directly release singles on YouTube or Spotify, so the albums organization doesn’t work that well anymore.
On top of that, the content you find in the trackers is very heterogeneous, entire albums as a single track, discographies as zip files, different file formats, single albums… and it seems to confuse lidarr all the time so it cannot figure out what is what.
What do you use for your music collections? How do you organize them?
My uneducated guess would be that, overall internet speeds have increased enough that streaming is feasible for most people and that there is a lot of healthy competition in music streaming, where almost all of the major competitors have nearly identical libraries, so you don’t need to pay 10 different subscriptions for music.
Additionally, there exists services like tidal which offer lossless streaming so even the hardcore people can get all (most) of their music legitimately.
Basically the music industry did the opposite of the movie/tv industry and generally figured out streaming a long time ago.
