1.6 up and running, seems to be working just fine here and haven't found a case yet where top of scale wasn't matching top of song frequency, checked with Spek. Hopefully Mr. Trev is good too.
Different behavior: 1.5 used to load the placeholder.png immediately on start, before any stream or file playback was started; now it does not. Actually now is expected behavior so don't try to "fix", haha! Just like to indicate any differences I've noticed betwen builds.
Great work man.
