These are the audio files for I Don’t Want to Miss a Thing. Download the file for your part, plus the file that is just called I Don’t Want to Miss a Thing , which has all parts.
An MP3 player should recognise the files as being part of an album called MCC July 2013.
In terms of instruments used, the file with all parts has all the voices using a voice sound, no piano part for this one. In the individual parts, only your voice part is played. Watch out, as there is a small delay before there is any sound.
