Hi.

Recently I've decided to undertake the task of aquiring all the BGM test music. Currently I am missing a meager 3 songs. I am wondering if anyone could tell me how to get them.

Here's the order of the songs I'm missing.

Valentine
?????
After the Story1
?????
Can still see the light (ending theme)

and much farther down...

"Idola" have the divine blade.
?????

I'm thinking the last one is for beating Olga Flow.
Which I can't seem to do solo (despite being lvl 54) I was wondering if I could still get the song if I defeated Olga Flow in co-op.

Thanks for all the help!
