- Metallica rip-off riffs.
- Slayer rip-off riffs.
- Morbid Angel rip-off riffs.
Please note that I don't take offense to a band wearing their influences on their sleeves, but those 3 bands get their riffs lifted, almost note for note, chord for chord all the time and it's getting pretty fucking old.
- Drummers that rarely/never throw in fills.
- Movie sample song intros.
- Songs that reference other songs in the lyrics. Unless all songs in question are part of a concept album. Otherwise, it's just fucking cheesy.
- Weak assed guitar tones. Guitars need to have a distinctive crunch (not necessarily chugga-chugga shit, just a beefy tone).
