That they are. Every stage I'll pick (with the exception of Lylat and Castle Siege) has every in-game tune replaced.
All of my custom music (BRSTMs) have a tiny bit of silence in the beginning of the song. Occurs both when in My Music and on the actual stages.
I know it's not too much of a bother to most people, they can deal with half a second of silence, but I can't. And sorry for being.....is it off-topic?
... So no one knows how to fix this? '_'
By the way, the bit of silence only occurs in some songs. The rest are fine. Menu 1 lags for me, but Battlefield V2 is fine. dafuq?
