My mom only knows "I Kissed a Girl" as a Katy song, though I know she's also aware of other Katy songs, even if she doesn't know that they're Katy songs.
0. I don't think my parents can name any songs by pop girls (or even name the pop girls' names).
The only one my mom would be able to name (I think) is Alejandro by Lady Gaga. She also likes Umbrella because of the "ella-ella" parts (which is her name ) but I don't think she'd be able to name the artist of that song,
