There are numerous complaints about the inability to see an entire song name if it is long. This is a particular problem with classical music, in which you can't tell which movement a selection represents, but it can be a problem for any song with a long title which isn't displayed in its entirety.
I've found that the way to see the entire name of a song is to press the menu (. . .), then "Share," then "Post To." At this point you can see then entire name for the track. Wouldn't it be nice if the menu included a choice for "Info," which would display the full title? Or even better if a long press on the song would display the full title? It seems this could be implemented and would partially solve a big problem.
I do understand that real estate on the display is quite limited, so the solution isn't easy. This could be a big help, though.
I also have experienced this problem on the iOS app. I would very much like to see this issue addressed, especially since it has come up in multiple topics and suggestions in this community (a quick Google search yields several over the pay few years).
