As audio technology changes, so do the ways people listen to music. When music was mostly on vinyl albums, those large discs called records, music listening happened at home. The turntable used to play albums is not very portable. Eight-track tapes made listening to music in the car possible. Then devices got smaller, and music became even more portable. The invention of the Walkman portable cassette player meant a person could carry music everywhere. Portable CD players were also easy to carry. However, they often skipped if they were bumped. MP3 players are still relatively new and are the most portable music option of all. A person with an MP3 player can carry as much as 40 days worth of music at once and never have to worry about the music skipping.
