I can recommend Green Grass and High Tides from RB1 which has about 250.
Last by NIN also has quite a few. (DLC)
If you're playing on Medium I really doubt there's an efficient time-saving method of getting this achievement. For the "85% guitar solos" achievement I took Rainbow In The Dark and Crazy Train down to Hard difficulty, and they had next to no HOPO's even though they're filled with them on Expert and I only went one difficulty down.
If Green Grass has approx 250 HOPO'S it'll take over 200 runs to get the 53k, you're looking at 36 hours worth of grinding doing that. I'd imagine it'd be more efficient just playing the songs you enjoy on Medium and improving passively, maybe throwing GG&HT into a setlist once a day to make some progress.
