I’m trying to combine several tracks so they become one continuous song. I’ve made all the edits on audacity in 4 separate files for the 4 songs. I just want to combine all the songs into one file where they play individually. PLEASE HELP ASAP

If you have the songs on top of each other in separate Audacity tracks, you can press F5 on your computer keyboard then drag each song so each one starts after the other. Press F1 to go back to Selection Tool when you have finished dragging.

Or you can do Edit > Select > All then Tracks > Align Tracks > Align End to End.
