Android auto app with fast forward within song

I have a lot of music with delays and intros that I would like to fast forward through but I can find an app that supports this. Does anyone know of any? I ripped a bunch of concerts where I'd like to fast forward through the chatter between songs. I can only find apps that skip to next song not within a song. Thanks.

 

Not about android auto app but with regular music play if you press and hold the up arrow on left side of steering it function as fast forward. Same with down arrow, to function as rewind.

 

I am meaning within a song file. I know the steering controls work but they still jump to the next file. I want something to skip to a certain point within the file or jump ahead 10-15 seconds at a time. I think that has to be a feature within the app being used. I have been trying various apps but have not found one with that feature yet.
