Doesn’t play offline and is slow – Meloman - Great Player Review

So I go traveling a lot and I want to find a good music app so can play my music in the the car but this doesn’t play offline and it’s very slow I press on a song and it takes about a minute to get the song on please fix to make it play offline he app would be so much better ?
