Amazing work (as usual), MAG!
A bug I found: I usualy listen to long mixes, and I noticed, that OMP does not handle songs correctly, if they are longer than 1 hour, seekbar is messed up in these cases, and time (both played, remaining and total) shows incorrectly.
Also, if Central European accented characters are present in a song's ID3 tag, they will show up as empty spaces in the playlist and will not play, instead OMP will start playing the first song in the playlist.
