Two questions: Which is the easiest way to concatenate music files? Which is the easiest way to concatenate mp3 files? Background: I am using a software that allows me to "Play" photos on a DVD player while playing either a MP3 or WAV file, (also recorded on the same CD). The software only accepts one music file and around 100 photos which take approximately 15 - 20 minutes to play (This is also a parameter to fix, U can fix, during the creation process, the number of seconds each photo is shown, and after that it cannot change). Most songs lasts 2 - 4 minutes long and even the most beautiful song u can imagine (Whatever that is) becomes unpleasant when played four to six times, continuously.
