Firstly, i purchased my track (Milburn - Lo and Behold) from itunes. I purchased it from itunes because this is the easy way to take the track and import it into final cut, only a couple of processes are needed, which can be seen below.
Before i can import the track into final cut, i need to convert it to a WAV file. I need to do this because the track will not function right if it is not done. First i highlight and double click on the track, then I scrolled down to create WAV Version and click on it.
Once i clicked on this, a new track appears below the original. The new track is the Wav file and now i could take the next step to import it into final cut pro. I then dragged the track into my desktop so i can easily find it later.
Next I opened my final cut document. I went to file - Import - Files.
I then find my track in the folder that i placed it in. I highlighted it and clicked choose. This should then import the document into final cut.
When the track was imported into final cut, it was placed into the area where all my footage was placed. I then simply dragged the track into the sound area of the editing area. The track now fits in with the footage.
