You can hardly hear the music that plays. There is no volume control, and the batteries were good.
Mickey has two buttons on the front. One to select songs. The other to play songs. A good selection of songs including the Hot Dog Song. The book has nice pictures and the lyrics.
My kid is ver fond of mickey and this take along book with player is a great one. it has all the poems that kids love and he is so fond it while we are travelling.
