Best practice for counting streams

Im building podcast app and I've question what is the best solution for counting streams? in postgres database should I just save array of people who streamed?
{
userId: String,
streamedAt: Date
}
{
userId: String,
streamedAt: Date
}
that comes in my mind as solution and is there any better way? (also that content must has analytics, dashboard and etc)

I would store the watched podcast on the user. Then if a user streams a podcast check if they did before by accessing their history and if not increment a streams counter on the podcast object. Probably not the best solution but it reduces database queries compared to your solution I would save the history with an array of podcast ids on the user

this is one of those times where denormalizing your db is reasonable
