I think the problem with a LOT of TNA themes is that they sound like glorified MIDI files (which they probably are). I mean, Daniels theme is just fucking awful. And Sabin? Do I even need to mention Sabin?
That said, they HAVE been getting better with the newer guys that have come in like Rhino, Cage & Angle. I'd still like to see actual songs (even if I don't know them) being used, though, as I stated above.
