Generates the content of a .cue file to distinguish several tracks in one audiofile. I used this for foobar2000 when having a single audio file that actually contained multiple songs.

print-cue-file-content.py

#!/usr/bin/env python3
"""
Prints out the content of a cue-file.
You can specify the performer, album, release-year, filename, fileformat
and of course the tracks with their lengths(!) and names.

Echo into a file or copy the output to a cue-file, e.g. python3 print-cue-file-content.py > trackinfo.cue
You can then open the .cue file with VLC, foobar etc.
