Do you know a music player from fdroid that does this?

So, I'm studying music and while reading and playing the scores I usually get stuck in some parts. Luckily I have the audio of what I'm supposed to play, and here enters my question:

I'd like to put a tag in a specific part of the audio, corresponding to an area of the score that I'm stuck, so that I could easily return and listen and compare with how I'm playing.
