They were so much more expensive than Pandora when I tried them out and the free tier was too awful to want to reward them with my money, so I did pay but it went to a competitor. Their music recommendations were terrible compared to Pandora, too.
I don't use Pandora now though, they got bought by SiriusXM who I will never pay again after they made cancelation such a difficult process.
That's when you put butter in the sauce to stick to the butter on the pasta.
