Is there a shortened method to loop through conditions in IF in VB.NET

So I am making a program that needs to check if a file is of Video / Audio format. To do this I have this code (Song is a System.IO.FileInfo):

If Song.Extension.ToUpper = ".MP4" Or Song.Extension = ".AVI" Or Song.Extension = ".MP3" Or Song.Extension = ".AA" Or Song.Extension = ".M4A" Or Song.Extension = ".AIFF" Or Song.Extension = ".WAV" Or Song.Extension = ".M4V" Or Song.Extension = ".AAC" Or Song.Extension = ".VOB" Then

The problem is that this only checks the first 2 conditions. Do I need to split this into separate Ifs or is there some way to test all the conditions in one line?

It seems to me that it would be easier to use a select case construct with just one case:

    Select Case Song.Extension.ToLower
        Case ".mp4", ".avi", ".mp3", ".aa", ".m4a", ".aiff", ".wav", ".m4v", ".aac", ".vob"
            'Do something
    End Select

You can make a set with all the extensions in it:

Dim extensions As New HashSet(Of String) From {
    ".mp4", ".avi", ".mp3", ".aa", ".m4a", ".aiff", ".wav",
    ".m4v", ".aac", ".vob"
}

and check if a value is in it with Contains:

If extensions.Contains(Song.Extension.ToLower()) Then
    ⋮
End If
