Remove Picture Preview in Album for certain file types

[Several Zombies]

I was just wondering if it's possible to disable the "Picture Preview" in Albums if the file you're looking at has a non-image extension. For example, if I were to add the .mp3 extension to the list of acceptable file types, when I upload and view the attachment, it will display a large empty box with a broken image (as the file is not an image). Is there any way to gate which file types display previews? The other option is to remove the block from the template entirely, which would mean that even files with image extensions would not be previewed, either.
