But we're talking big picture here, from the perspective of the consumer. Remember, from a consumer perspective, the business plans are more or less irrelevant. And when it comes to which streaming platform is more popular among the under 35's, it's relevant to platforms that Radio uses, like IHeart, TuneIn (and its competitors), & Audacy.iHeart and Pandora are in two very different businesses, even though they each use the internet. Same with Spotify and YouTube. They are not comparable. Just as Pandora and Sirius are two very different businesses owned by the same company.
YouTube definitely is different from all the others. It's a video / audio free for all there. I don't really know how Amazon and Apple Music operate -- never looked into it, don't have friends that use those services.
That aside, from the consumer perspective, how are Pandora and IHeart and Spotify not comparable? They all stream music. They all are streaming platforms with multiple, formatted 'channels' (Spotify calls them 'playlists', and their Pop section has 35 of them; IHeart has 21 "Genres" playlists and also others divided into moods, decades, etc.; Pandora -- which I've used, as it's on my phone
IHeart advertises its pre-formatted, genre based channels on their OTA radio stations.
Obviously, IHeart has literal radio station streams, where Spotify and Pandora and YouTube don't. So in that respect, you are absolutely correct. But the other platforms, especially among the under 35's, are presently eating IHeart's lunch. And what percentage of those 8% of under 35's listening to IHeart are tuning into IHeart's radio station streams? I can't find any data on that.
Of course, these listening percentages could change. I still think that the streaming field is still in the shakedown phase. We've got people getting their audio from OTA as well as their smartphone now. As the years progress, it's going to gravitate more towards phone-only.
