I don't know an awfull lot about theory and scale names but I'm using minor, major, pentatonic, harmonic minor, arabian and yona nuki so far... at least I think that's what they are called (I don't know, maybe some of those extra notes are accidentals or something)... also some chromatic runs. One thing to watch out for though is that the backing track changes a few times from minor to major. The way I'm looking at it is to break the track down into a number of independent lead passages over the various riff changes. It's a challenge as I've never played in this key before but the patterns are the same, just different frets.

I'm using my ear to work things out, maybe a theory expert out there can explain the keys and scales??
