"I Wanna Be Your Man"

This morning, I listened to the second disc of Anthology 1 and noticed a few things.  There's something of a lyrical ambiguity in "I Wanna Be Your Man."  "Baby" in the line "Love you like no other, baby" is probably meant as a vocative because this is how it functions in other lines ("I wanna be your lover, baby" and "Tell me that you love me, baby"), but it could also be understood as the comparative element (with "other" functioning as a true adjective rather than as a substantive):  "Love you like no other baby."
