I want to input user name and password once for 1 playlist

[canda]

I must input user name and password for each items in the playlist file (.m3u).
For example, the playlist contains as the following.
http://URI/path/song1.m4a
http://URI/path/song2.m4a
http://URI/path/song3.m4a
http://URI/path/song4.m4a

When the site needs user ID and password, I must input 4 times.
If they are the same site and same username and password, I prefer to input once.
Does VLC have some setting to resolve this?
Or Other solution exists, I want to know.
