I'll try to walk you through what I'm actually hearing that makes me think there's Auto-Tune there:
- 2:50: Subtle, but as the first "oh" starts, it sounds like it quickly jumps from a slightly lower note to the correct one.
- 2:58: The word "part" has a classic Auto-Tune sound. The real recording probably went slightly off pitch as the note was held and Auto-Tune has made it perfect and a little robotic.
- 3:07: "Where" has a similar sort of robotic pitch slide sound as it starts as the "oh" did earlier.
- 3:13: "Discover" has a sort of a glitch in the middle as Auto-Tune tries to track across the 'k' sound in the middle of the word.
As someone else already said, songs in TV show Glee used it all the time in a fairly obvious (but still subtle compared to intentionally sounding Auto-Tuned) way.
