[This might not be the right place for this]
Has anyone tried, [url]https://play.google.com/store/apps/details?id=com.geecko.QuickLyric&hl=en[/url], Quick Lyrics with music playback using MMA? It seems to work very well - either finding lyrics as one song moves to the next in playback - or the user can use a "Refresh" icon to move it on to forward manually. I was wondering if anyone has tried Shazam to do this? It would be nice if one of these apps has pros and cons over each other.
