All perfect praise be to Allah, the Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
There is nothing wrong with using scented antiperspirant and musk on the clothes or the body for men and women (during the daytime in Ramadan). That is because such things are not solid substances, whereas what invalidates fasting is every substance that has a solid nature and reaches one's stomach.
As for listening to songs, it is a prohibited and wrong action whether in Ramadan or other times. It is one of the causes of heart diseases and their (the hearts) hardening and even averting them from the remembrance of Allah Almighty.
It is not permissible for a woman to wear pants, whether in Ramadan or other times, unless she is with her husband only. That is because pants are mostly tight fitting and outline the body curves.
If the pants are loose fitting and cover all of the body, then it is permissible for a woman to wear them before women, although modesty is more appropriate for woman.
It is worth noting that the fast of the one who listens to songs and of the woman who wears pants before foreigners is valid, but they are sinful due to committing what Allah Almighty has prohibited.
Allaah Knows best.
