Small problem with what seems to be simple code in IE

[kila_bite]

Just to say this code works perfectly fine in Firefox, however in Internet Explorer it doesn't seem to want to work.

My problem is simple: I offer game OSTs on my web site for download. For some reason now, when ever somone attempts to download an mp3 from my site in IE, no download window appears and if they use the "Save target as" function, for some reason it wants to save as a .htm document even though the extension is clearly .mp3.

Site is: http://www.finalfantasy-net.com

My OST list is: http://www.finalfantasy-net.com/ostlist.php

And an example problem is: http://www.finalfantasy-net.com/cast...sorrow-ost.php

I'm really hurting for help so please, if you have any ideas or suggestions for an alternate download system if this can't easily be fixed let me know, for instance and FTP session download system that I have seen other sites use?

Thanks in advance.
