Theres no more songs I can play..

Characters are cute.
Game is fun. And I can add new song just from my own music list, to generate new stage automatically.
And this stages are perfectly matches with almost every songs.
This game create another new stages, like this way.
I added 14 new songs and I earn 5 stars for each songs already.
But, I cant add no more new songs because I had to spend 10 passes for when I add every 1 song slots.
14 new songs are not enough for enjoying this game long.
But its only way to going to new stages.
Nothing else there.
But, I dont want spend $4.99 to add 2 SLOTs to just add songs from my music list already bought.
