Pacopacomama 050710 084 Ikuko 15 -

I should also consider that "ikuko 15" could be a track title. For example, an album called "Ikuko" with track number 15, or maybe a song titled "Ikuko 15" by Pacopacamama released on May 7, 2010. Since I don't have access to specific databases, I need to infer based on common patterns.
