I have been using this app since 2015 and it is the only app I have ever paid for on google play store. I have had no problem with this app and it is best music app out there. The only problem I occasionally face is that when sometime I add album art to my music files, my sorting list is changed because the file's date modified has been changed and I like my list with latest music on top.
Therefore, I request the developers to add a feature where it sorts the library based on "date created" rather than "date modified". I would be forever grateful to you guys. Keep up the good work. Thank You.
