Song and podcast are constantly shown as not downloaded, and I have to force kill and clean the cache, several times per week. I noticed a global slowing down of the application. I also found it unpractical that there isn't a place to see all your (downloaded) music. In addition, I cannot explain why there isn't the useful gesture to add a song to queue as there is on iPhones. Finally, it would be great if one could use alternative client, such as with reddit, etc.
