yes, audo.info.length is the time of the mp3 in seconds,
int(audio.info.length) makes it a whole number

isn't that just a counter of sorts as well? I discover the error of my ways,
I was putting an unnecessary while: ahead of everything, the easy-for-me
solution to self-terminate when the song finished playing was
mP3 = sys.argv[1]
from mutagen.mp3 import MP3
audio = MP3(mP3)
cycle = int(audio.info.length)
x = 0
for i in seq:
GPIO.setup(i, GPIO.OUT)
GPIO.output(i, GPIO.HIGH)
seq.reverse()
try:
while True and x < cycle:
for i in seq:
GPIO.output(i, GPIO.LOW)
time.sleep(SleepTimeS);
GPIO.output(i, GPIO.HIGH)
time.sleep(SleepTimeS);
GPIO.output(i, GPIO.LOW)
time.sleep(SleepTimeS);
GPIO.output(i, GPIO.HIGH)
time.sleep(SleepTimeL);
# 4 seconds to cycle loop
x = int(x + ((SleepTimeS + SleepTimeL) * 3.5))
