One thing that I would like to see implemented is the abilty to display lyrics in all of the apps. For those of us who have libraries with lyrics embedded in the actual files, it would be trivial. Simply scrape the lyrics from the lyrics tag and display them.   As far as scraping from online lyrics databases, I don't see that working very well as just about every app that I have seen use it either doesn't get the correct lyrics or they are truncated with an add for the website.
