What offline local music players (other than the native music app) are people using these days

Hi,
I'm just curious, I know more and more people are streaming music these days, I do sometimes, but I have stuff that's extremely rare and not available on streaming services. What offline music players are people using these days, aside from the music app? I'm using jet audio, which I like, because it has the crossfade player (can't stand any gap between my songs, I'm spoiled). It also has a playlist feature. But I'm just curious what people are using these days to play offline music?
Thanks
