Pop. I know Achtung and JT are better but my favourite experience is Pop. I can get lost in that album, start to finish (save for The Playboy Mansion, which I often skip).
The songs are amazing, Disco has so much funk, Do You Feel Loved has an awesome groove, Mofo is just sensory overload (still finding new sounds in it to this day), IGWSHA is chillin, SATS is a good singalong. Gone is solid, Last Night is rocking. Miami is the coolest song ever recorded, and the centrepiece of the album for me. Velvet Dress is dark and sexy, Dead Man is angry and poetic. And Please, well for me they nailed it on the album version. I love the single version but the sounds in the Pop track are just haunting, it really feels polished and genuine.
The Pop experience - there's blood in the music.
