Is it possible to download some songs from iTunes onto my env2 phone?

[horsechic1990]

I just got the new Verizon env2 phone, and my sister got an iPod shuffle. The env2 uses a program called Verizon Music Manager to download songs onto the phone, and the shuffle uses iTunes. Is there a way to take the songs I want off of my sister's iTunes account and put it onto my env2? I would love to use some of her songs on my phone, but I don't know how to transfer them from iTunes to Verizon Music Manager...
