You want me to tune a classic?
I don't understand ..
Download *which* All Day and all Night?? There are more than 1 there.

As for tuning; every word will be different in cents .. that's why these plugins work as they do. What you are attempting by moving everything a certain number of cents is called pitch shift (constant shift over whole thing)

Tuning adjusts each note a varying amount, even varying on each inflection depending on setting ..
I seem to recall thinking GSnap didn't work at one point also, but there was some setting I had to check, maybe even adjust the threshold or error correction threshold.
Or select a preset .. something made it kick on.
Since getting other tuners I haven't reloaded GSnap on recent systems, so I can't test.

Make your sound your own!
.. I do not work here, but the benefits are still awesome
