Answer 1

you can try Environment.GetFolderPath

//if you want windows common music folder ex:C:\Users\Public\Music\streamfile.txt
var CommonMusicPath = Environment.GetFolderPath(Environment.SpecialFolder.CommonMusic) + @"\streamfile.txt"; 
//if you want windows user music folder ex:C:\Users\username\Music\streamfile.txt
var MyUserMusicPath = Environment.GetFolderPath(Environment.SpecialFolder.MyMusic) + @"\streamfile.txt"; 
using (StreamReader sr = File.OpenText(MyUserMusicPath))
{
    String s = "";

    while ((s = sr.ReadLine()) != null)
    {
        Console.WriteLine(s);
    }
}
Console.ReadLine();

There is a list with 'special' folders somewhere but you can construct it yourself:

  string path = Path.Combine(Environment.GetEnvironmentVariable("USERPROFILE"),
           "Music", "streamfile.txt");
