Needs to work without WiFi

This app is pretty good, but it needs to be functional offline so I can listen to music on the go. It also has little bit of bugs in it, like when I scrub the timer of the song, it stops and sometimes restarts and freezes itself. Also when I try to repeat and listen to my favorite songs, it restarts and freezes as well. Id appreciate it if this works without wifi.
