Ok..

I like this app, its good for listening to Vocaloid and anime theme songs, but it really needs some improvements.
1. Fix some bugs: Sometimes Ill be listening to music(even on wifi)and the app crashes and the music stops. And I have to refresh the app. Its really annoying. Please fix the crashing!
2. Have an offline mode: I really dont want to waste data every time I want to listen to Vocaloid off wifi. Maybe you could have the songs you put on your playlists be offline.
Other than that the app is good but it could really use some updating. Please fix it
