will people recommend me HOPO heavy songs.

[Svarta Varg]

for guitar, bass and keytar i'm looking mainly for ones similar to how some of these following songs are not highly difficult ones like caprici di diablo

amberian dawn - dreamchaser (parts like the intro)
http://www.youtube.com/watch?v=Q0YBJy70Xg0

eths - adonai (the verse and to a lesser extent the chorus)
http://www.youtube.com/watch?v=Myx_aGN4bLw

eths - gravis venter (the intro)
http://www.youtube.com/watch?v=ICpw5iuSRFg

yogurt with sprinkles - version 2 (2nd half of the key solo when played as keytar is all HOPO)
http://www.youtube.com/watch?v=Hu-MzyK5ilw part i'm talking about starts at about 3:16

[BohemianMatt]

"Stash" - Phish
"Diary of a Madman" - Ozzy Osbourne

Two I can think of right now.

[LiveHomeVideo]

If you play on Rock Band 3, "Aesthetics of Hate" by Machinehead. They actually changed the song's HOPO ratio between 2 and 3.

Rude Mood by Stevie Ray
Obfuscation by Between the Buried and Me

[SheSaidSheSaid]

No Woman No Cry
Everybody Wants to Rule the World
Red Barchetta
Alabama Getaway
Dig
Here Without You
When I'm Gone
Blurry
Something Bigger, Something Brighter

All HOPO-heavy, none of them "OMFG THIS IS HARD!" level of difficulty (SBSB is devil-tier, but it's really not that hard. And...fine, skip if you want to ).

Rude Mood by Stevie Ray
Obfuscation by Between the Buried and Me

OP said no "highly difficult" songs.

Rude Mood by Stevie Ray

he said not too hard

[GNFfhqwhgads]

Joker & The Thief has 632 HOPOs or something.

[Alternity]

I don't find these ones too hard, I find them fun :|

[SheSaidSheSaid]

Good for you, you're a guitar god. Rude Mood is one of the most difficult songs in the catalog (top 5 or 10 percent anyway). There's no way you didn't know that.

[Alternity]

Dreamchaser is harder than those IMHO.
