It's often a bad idea, but here's some when I used it:

- Widget labels (time, short text, etc)

- Buttons, when text is just an arrow >

  (I know, just use <button>) :)

- When double click makes accidental text selection on UI. I had this for a whole page overlay displaying a song's artist and title. (there's another link to the source with selectable text)

- Navigation, but that might be bad too
