content: This is excellent music for "Punch Drumming", or hitting the speed bag too music. Many of the songs have a great beat and just enough instumental melody line to give you a "groove" while your bag beat plays around the melody. Blow Out, High Roller, Keep Hope Alive and Cherry Twist - ALL great songs for the "bag beat". And when you're done punching, it's just great music to listen to and groove on. Light yet rhythmic. I like it!
