Is this normal ?
No, that's not allowed. Which is the correct song title?
The correct song title is The Breaking of the Fellowship (In Dreams), Juan. The thing is, In Dreams is a small song included in that long instrumental piece (The Breaking of the Fellowship), the same way Enya's May It Be is included in the final track of that soundtrack. She did release the song on her own, though and a separate version of the track exists so there's no problem with it.
