it's free and 100% human, I recommend NTS Radio, which is web-based and has a huge archive of recorded shows in many genres and topics. Bandcamp and Soundcloud also have playlists that feel more carefully curated than Spotify's I think. oh and college radios are a great place for discovering new music too. There's a site called campus-fm.com that let's you tune into different ones across the US :)
disclaimer: i work for a radio station
