You have multiple options, many outlined previously.

A few more options:
Map the KB shortcut for "Play Selected Range" to the key of your choice.

Select what you want to play, then press your shortcut and it will play. When you press it again, it will restart at the beginning.

****
Use Looping without manually creating the loop
Turn on "Loop follows selection" (right-click Timeline, or use shortcut keys)
Select your set of bars (If Snap to Grid is On, it will get right to the barlines.)
With Looping "On" it will loop over your selection, 10 bars, 2 bars, or whatever
Select next section you want to loop/listen too, press spacebar to start and it will loop over that area.


Use Mouse:
Double-click in the Timeline will start playback at bar 55 (or wherever).
Don't move your mouse after double-click (playback starts) Single click if you want to replay, and the cursor jumps to your single click point when playback is already in progress.

Any of those can be added to a Macro button if you wish...

Play Start Marker would allow you to set start point, and a double-tap on the spacebar would go back to your Start Marker and continue playing.


TOOO Many options, use the one that makes the most sense for you...
