Should I try and rank position no 2?

Tricky one this

I have different versions of a song I'm promoting on my channel. When I put in a tag in youtube buddy for the remix version of my song it shows I'm already at no1 for that term with the original version of the song. So my question is should I still use that term to try and rank at 2 for the remix version or should I not try and rank for that keyword phrase at all-If that makes sense!
