Creates ID3 tags for your mp3 files based on their filenames. Simply splits the filename at the fist '-' and considers the first part as 'Artist' and the second parts as 'Title', so name your files accordingly.
You will need Maven to build the project.
mvn package
Re-tag all your mp3 files under a folder (not recursive):
java -jar target/mp3retagger.jar ~/MyMusic/*.mp3
