Updating 'altered' MP3s on phone?!

[Homey]

I'm sorry to ask this question as the answer is probably obvious to most (but not to me!)

Most of my MP3s vary a lot in volume so I discovered a program called MP3Gain to alter the playback levels so that they are more uniform.
The only problem is that the Zune Software does not seem to recognise that the MP3 files have been altered in any way and therefore refuses to update my Lumia with the new, MP3Gained files!
Is there any quick way to just update all the songs on my phone with the edited files automatically or do I have to delete all the songs and upload them manually?

Any help would be gratefully appreciated!

Sorry, but you have to do it the hard way...
