This link will lead you to all of the vocal guided tracks to practice along with.  In your script, you will see in bold when the track starts.  Some of the tracks are full songs, while others are just music and sound effects to read along with.

While it is obviously important that we perform just like the songs, it is equally important that our lines, when reading with a song, follow a similar rhythm.  Often times, the music will change with the dialogue between characters.  Sometimes the music will sound happy, then immediately change to urgent.  If our lines are not lined up perfectly, this will appear strange.

Once you have mastered your songs and lines with the vocal guides, move on to these tracks where you can practice along with just the background music.  These are the same exact files we will use for our performance.

The track names look the same, but you will notice there are no voices.
