Individual download, skipping issue

Pls make individual song download possible. Because app doesnt support this basic function , i should download whole album tracks or make playlist and add songs to download
Plus , when skipping to next track, theres a short delay like when i use old mp3 player..its not really a big deal when next track has nothing to do with previous track but think youre listening to whats going on by marvin or sgt.pepper by beatles.. Its like hell..
i want this process to be more smooth. apple music app does this great but gpm..
