In terms of difficulty for each instrument
Easy - Same riff, doesn't sound hard, it's mostly holds.
Vocals are simple and in the same tone.

Decent - Some solos here and all, not that easy but it's still passable.
Vocals change here and there, and even has a long note or two, but nothing to make your throath die on you.

Hard - Guitar/Bass/Drums HEAVY, we are talking about long solos and complicated riffs, as for Vocals it would be Long and High notes and changing pitches drasticly and screaming with a certain note or holding like an opera note for a long time, difficult rap is included here too.
