I’ve been using it for years and I finally got Pandora Plus. I think it’s worth it because the ads are getting ridiculous. I don’t buy music or use Spotify. I think Pandora has a good system because most of the songs they play on my station I enjoy.
Yes I love Pandora. I don’t love Chance the rapper or the police that much but I really like their stations.
and much more
I don’t have premium though
Yes the ads are ridiculous and very obtrusive. I’m finding that’s happening with all my free streaming music sites. 
I like Pandora, though I typically put it on to fall asleep to.
I use Pandora when I’m on cable wifi, so I don’t use it too often. I noticed the ads the last time I was on it.
