I use Sound Studio 3...really long and generous trial period so I'd at least try that out. Here's how I track once you have the file open...
1) Command-0 will zoom out to see the full waveform in the window. Zoom in using Command-+ until you can pick out more or less where individual songs begin (Command-- will zoom back out one step).
2) Click to position the cursor where the song begins. Hit space to start playing, and use the arrow keys to move the cursor around until you're exactly where you want to split the first track (space will always start playing from the cursor, so you can keep moving around and hitting space to find the exact spot you want).
3) Make sure the cursor is stopped and hit Command-M to drop your first marker.
4) Repeat steps 2 & 3 for the rest of your markers. Add fade-in/fade-outs as desired as well (under the Filter menu).
5) Click Edit > Split by Markers, choose your output folder, and watch the program churn away as it splits your files.
That'll get you tracked files. Then fire up xACT (
