Ran it on Juicy by The Notorious B.I.G and results were considerably worse than my mix of prog-rock and british invasion music I had tried before, though at least some of that is due to the number of proper-nouns in that song.
It took about 1000 CPU-minutes for this 5 minute song on my Ryzen 2700 with 12 OpenMP threads (about 100 minutes wall-clock).

[00:00.000 --> 00:27.000] We're no strangers to love You know the rules and so do I
[00:27.000 --> 00:35.000] I feel commitments while I'm thinking of You wouldn't get this from any other guy
[00:35.000 --> 00:43.000] I just wanna tell you how I'm feeling Gotta make you understand
[00:43.000 --> 00:47.000] Never gonna give you up Never gonna let you down
[00:47.000 --> 00:53.000] Never gonna run around and desert you Never gonna make you cry
[01:00.000 --> 01:09.000] We've known each other for so long Your heart's been aching but you're too shy to say
[01:09.000 --> 01:17.000] Inside we both know what's been going on We know the game and we're gonna play it
It was running for quite a long time (20 minutes) on my admittedly low-budget specs.
Note that I did not omit 00:53.000 -> 01:00.000.
Shouldn't there be some type of unintelligible warning since it wasn't able to transcribe that part?
Model small is about as good at recognizing lyrics as an untrained Newton was at recognizing handwriting.
Here's a comparison of Basket Case by Greenday:
Small:
[00:00.000 --> 00:05.000] Do you have the time to listen to me whine
[00:05.000 --> 00:10.000] About nothing and everything I'll have once?
[00:11.000 --> 00:16.000] I am one of those melodramatic fools
[00:16.000 --> 00:20.000] Neurotic to the bone, no doubt about it
[00:23.000 --> 00:27.000] Sometimes I give myself the creeps
[00:27.000 --> 00:32.000] Sometimes my mind plays tricks on me
[00:32.000 --> 00:38.000] It all keeps headed up, I think I'm pregnant
[00:38.000 --> 00:43.000] And I'm just paranoid, I'm just stuck
[00:47.000 --> 00:52.000] I went to a shrink to have a life like my dreams
[00:52.000 --> 00:57.000] She says it's like a sex that's bringing me down
[00:57.000 --> 01:03.000] I went to a whore, he said my life's a bore
[01:03.000 --> 01:08.000] Choked with my widest buzz that's bringing her down
[01:10.000 --> 01:14.000] Sometimes I give myself the creeps
[01:15.000 --> 01:19.000] Sometimes my mind plays tricks on me
[01:19.000 --> 01:25.000] It all keeps headed up, I think I'm pregnant
[01:25.000 --> 01:30.000] And I'm just paranoid, I'm just stuck
[01:30.000 --> 01:48.000] Grasping to control, it's all I better hold on
[02:08.000 --> 02:12.000] Sometimes I give myself the creeps
[02:13.000 --> 02:17.000] Sometimes my mind plays tricks on me
[02:18.000 --> 02:23.000] It all keeps headed up, I think I'm pregnant
[02:23.000 --> 02:30.000] And I'm just paranoid, I'm just stuck
[02:53.000 --> 03:13.000] Thanks for watching!
