what's the best way to loop an audio file

I tried researching this here and online other places but all the answers I could find seem to be from some time ago, and aren't really what I'm looking for, so I'm asking now in case there are new features or ways to do what I want.

Very simply, what I want to do is have an audio file repeat all the way through a video. I don't care about fading or transitioning the beginning and end at each repeat point. I just want the file to repeat all the way through as is.

I recall in the past, and this might have been from a different video editing software (maybe it was Vegas Pro), I could simply drag the clip length longer and the frames (either audio or video) would just start over and keep repeating as long as I wanted. Is this possible in Adobe Premiere Pro?

Or is there a similar technique?

Or, is the answer still the only one I could find online which was that I need to copy and paste the audio file 50x on the timeline?
