When you lack outlets to shout your frustrations, music can be a convenient and cathartic release. Musicians often use music as an avenue to vent their discontent, whether personally, socially, or politically.
Songs like Losing My Religion by REM, or Creep by Radiohead deal with the feelings of loneliness and isolation.
Turn! Turn! Turn! by the Byrds exemplifies a statement of discontent by protesting against the Vietnam War.
A time to build up, a time to break down
A time to dance, a time to mourn
A time to cast away stones, a time to gather stones together.
