Most of them are cheap though. Like Spotify at ~$10 is nothing, you can barely get a beer for that in the city these days. That’s far cheaper than you used to pay for CDs!
Netflix really took the piss though - with the charging for no ads, HD and multiple screens. Then it gets to like $30 a month which just isn’t worth it with the diminishing library, so I cancelled that and use Amazon Prime Video for now as it’s still cheap in my country (and has no ads for now).
