I could be cynical and suggest you might need to actually listen to each individual song to determine what is needed, rather then adopt such an industrialized approach, but … here are my thoughts:
By “presence”, do you mean EQ? If it’s the same preset, then just put each song on a seperate track in a Cubase project, copy the EQ setting to each track and render each to individual files.
Do you have the right tool for the job? This is an easy task in a mastering application such as WaveLab.
WL Elements doesn’t have the flexibility of the batch processor in WL Pro, and yes, that only makes sense if you can justify the expense. If the songs all sound OK with the treatment you have applied on a single track, then lovegame’s idea is a good one, you can read up on exporting the cycle marker ranges here (under Export Range).
