Arlo: A what?
Lucy: An eight tract tape! 
Lucy: Spotify keeps talking about it.
Arlo: Well, let me google that for you...
Lucy: Smartass...
Arlo: Well!
Arlo: It is exactly what it says. A cassette with a tape in it that has music recorded to eight tracks.
Lucy: Weird.
Arlo: They were popular in the 70's but replaced by cassette tapes.
Lucy: What's that?
Arlo: You are such a baby!
Lucy: Sorry!
Arlo: Another, smaller tape style way to listen to music.
Lucy: Oh. So they were sticky?
Arlo: No! God!
Arlo: <file_other>
Lucy: Oh, weird! You had to rewind?
Arlo: Yep.
Lucy: Much better now!
Arlo: Maybe... I miss the art and actually holding the music in your hand, but whatevs.
Arlo: And miss listening to a whole album, as intended.
Lucy: Mkay...whatever!
