It is either or
Ne! is very good song. I like that it has jazzy feel in it, mixed with rockish feel. And it is very positive.
Goodbye Esaka is like very good popular music song, that should be in Top 10. And it has very "goodbye" feel on it, that almost makes me sad. Of course I hadn't even heard about SNK on that year.
But which one is better? Goodbye Esaka doesn't get boring as fast as Ne!, but on the other hand I like jazz.
