For my iTunes, I just have all my stuff grouped by album artists, so I put her as V V for album artist for her old stuff but keep V V Brown for the artist. That's what I did for Cheryl Cole when she dropped the Cole.
Thought I had commented in here but I haven't lol I love the song and I'm pleased that her work is continuing to be great. Samson & Delilah will be incredibly hard to top.
