Should I use 'cues' or 'wavs' for music/sfx?

I know cues can do some fancy things, but if all I want to do is play a song, is there any downside to using a wav, or plus-side to using a cue that I should know about?

Most importantly, is one more or less performant than the other, and why?

Thanks!

No you don’t need to use cues if you don’t plan to use there feature in fact it’s kind of wasteful to use cues in such case (but not noticeably). all UE4 functions use SoundBase class to pass sound asset, which can be normal Wave, Cue or anything else that can be sound that UE4 supports and from plugin you got, it was made that way. So if you make sound property use SoundBase instead of SoundCue or SoundWave and it will support both, you can see class tree here showing that:

That was super informative! Exactly the information I was looking for! Could not have been more helpful. Thank you !
