   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))
