I've been there Jimmy and have tried several ways of dealing with this issue, each with its own pros and cons. In addition to the suggestions already made....
You could keep all the material in one project, but do the following:
- Create a separate track folder for each song, and name the folder accordingly
- Duplicate all the tracks into each folder
- trim the tracks for each folder so that they represent the folder's song title
Now you can use the folders to reduce screen clutter, and only expand the folder for the song you are currently working on.
If you find you that certain settings and FX are identical across several songs, then create busses for those and route the tracks accordingly. The busses minimize duplication of effort and the tracks allow you to do specific settings that are required by any given song.
When you're done, you can then choose to export the entire collection of songs as one mixdown file, or export several parts by simply highlighting any given track folder and exporting just that song.
