try a ii instead of a IV, and i think you'll find it fits way better. the minor V works really well in this song because it's the equivalent of doing a i-V-I progression - a picardy third, if you will. for what it's worth, i don't think it's really a minor V chord, i think it's a ii sus chord with the sus in the bass. there really isn't a classical way to write that because it'd break so damn many rules, but it sounds cool - it's popular in modern music only, you'd never see it in traditional writing.
for a guitarist, it'd look like this: B C#sus/F# C#m F#.
B D# F#
F# C# F# G#
C# E G# C# (might be a seven in there, i can't quite hear it)
F# A# C# F#
