Unzipping several specific files out of many into a directory using the terminal?

I recently installed Linux Mint 17 on my laptop. I had Windows 7 before, and I backed up all of my data onto an external hard drive. Windows 7 crams all of your backup data into a ton of .zip folders. Here is my problem: I only want to extract those folders that contain my music, which lie in the path 'C:...\Username\Music...'. So I tried to find a way to use the unzip those files from my external hard drive and into my Music directory in my home folder using the terminal. I am still learning how to use the terminal, but this is what I have found:

for file in *.zip; do unzip -c "$file" -d "/~/Music" | grep "\Username\Music"; done

It gives me the output:

caution: not extracting; -d ignored

When I remove the '-d', it works, (well, seems to work: it ran for a while), but I get a weird output at the end and then this:

62;9;c62;9;c62;9;c62;9;c

I searched for the music that was supposedly unzipped but could not find it. Can anyone tell me if and how I can accomplish my goal? I'd like to unzip only my music files from my external hard drive to my Music folder.
