Thanks everyone! Proud to join the Phish nerd hall of fame! My whole life has led to this moment.

What a tough puzzle! I wouldn't have gotten anywhere without the hint, considering that 3/4 jams were not in the jam charts. Like some others have commented, I was also a little distracted by the other possible meanings of the hint (Lou Reed covers, versions of "Rock and Roll", Rolling Stones covers, It's Ice, musical costume songs, 50 Cent covers, etc.). I think that made the puzzle even better. Luckily for me, I guessed right and searched generally for cover songs.

Anyway, thanks to @Dog_Faced_Boy for putting it on this week! Looking forward to seeing what has in store for round 3 of the MJM madness!
