Answer 1

ok thanks keyboardP for your help ;here is my code
protected void SaveMusic(Stream stream,string name)
{
IsolatedStorageFile fileStorage = IsolatedStorageFile.GetUserStoreForApplication();
if (!fileStorage.DirectoryExists("Source/Music"))
{
fileStorage.CreateDirectory("Source/Music");
}
using (IsolatedStorageFileStream fileStream = IsolatedStorageFile.GetUserStoreForApplication().OpenFile("Source\\Music\\" + name + ".mp3", FileMode.Create))
{
byte[] bytes = new byte[stream.Length];
stream.Read(bytes, 0, bytes.Length);
fileStream.Write(bytes, 0, bytes.Length);
fileStream.Flush();
}
}
protected void ReadMusic(string name)
{
using (IsolatedStorageFile fileStorage = IsolatedStorageFile.GetUserStoreForApplication())
{
songStream = null;
songStream = new IsolatedStorageFileStream("Source\\Music\\" + name + ".mp3", FileMode.Open, fileStorage);
}
}

Answer 2

Assuming your saving and reading code is correct, your stream's position might be at the end. Try adding
songStream.Position = 0;
before SetSource(songStream);
Try using this to save the file:
using (var fileStorage = IsolatedStorageFile.GetUserStoreForApplication())
{
var buffer = new byte[1024];
using (var myIsStream = fileStorage.OpenFile("Source\\Music\\" + name + ".mp3", FileMode.CreateNew))
{
int bytesRead = 0;
while ((bytesRead = stream.Read(buffer, 0, 1024)) > 0)
myIsStream.Write(buffer, 0, bytesRead);
}
}
