[3][4] SensMe works by using a twelve tone analysis of all the user's music individually, computing track information based on the mood and tempo of the tracks, and then outputting them for the user to play these automatically generated playlists.

Initially (on Sony Ericsson devices), the software would use a dual axis map which all the analyzed tracks are plotted into,[5] allowing the user to navigate to an area of the map to play a playlist or an individual track.

[6][7] In later devices, including Walkman DAPs and the PSP, the analyzed tracks are categorised into 12 "channels" that is navigable in a list,[8] with names such as Lounge, Upbeat, Emotional, and others.

[10] SensMe was made available on the PlayStation Portable as of system software version 6.10.

These include Favorites, Newly Added, Dance, Extreme, Lounge, Emotional, Mellow, Upbeat, Relax, Energetic, Morning/Day/Night/Midnight, and Shuffle All.
