Ok let's say I have a music album in .mp3 format, the whole album in a single .mp3 file. Is there a player for android that let's me skip directly to a specific time stamp? Like, have a bunch of time stamps "links" that I can press and it skips directly to it? Alternatively, some way to break up the single file into multiple files (songs) would also be acceptable

hi ZIGS Astro Player's bookmark feature seems to do what you want.

However, I would just unleash the power of FOSS and use ffmpeg for this like I do for everything else:

--- Code: ---
#!/bin/bash
set -e

# Start time/End time/Filename
SONGS=( 00:00:00 00:00:30 "dead poo poo.mp3"
        00:00:30 00:01:15 "killall poo poo.mp3" )

# Input file
INFILE="bigazzfile.mp3"

for ((i=0;i<${#SONGS[@]};i+=3)); do
  START="${SONGS[i]}"
  END="${SONGS[i+1]}"
  OUTFILE="${SONGS[i+2]}"
  ffmpeg -i "$INFILE" -c:a copy -ss "$START" -to "$END" "$OUTFILE"
done

--- End code ---
