Well, an interesting point they made was that those women (and a few men) were really restricted in what they could do before the 60s rockers said, "No, go ahead,
blow it out!" which freed them to really sing. Once they started really singing, they
did make some of the songs they sang on.
Gimme Shelter wouldn't be the same song without Merry's vocals, so credit where credit is due.
Not saying you're doing this
@d gray, but in general, people have a problem with women who dare to exhibit any ego. If Mick Jagger had done a backing vocal like Merry's on someone else's song, everyone would be falling all over themselves saying he "made the song." But when she lays claim to the song being great (which she didn't, but if she had), she's seen as being out of bounds. It's a double standard.
Girls to the front!
Darlene Love is a special case. Spector fucked her over for sure, and of everyone profiled in that movie, Love had - and still has - the most distinctive voice. One of a kind. She's the star of the movie, as she should be.
