Many words may be used to describe the re-use of MM2's "get weapon" music, but "brilliant" is not one of them. A 4-second single-drum track is not nostalgia, it is a sign that Inafune needs to get over his damn phobia of 3.
A 4-second single drum track is indeed nostalgia, being that MM2 is arguably the majority of old school gamers favorite MM game, or the first one a lot of MM fans started with, or the one a lot of people remember the most out of them all. I'm not saying it's better than MM3's at all, but since they were clearly going for MM2 nostalgia with MM9, it makes sense to use the MM2 Weapon Get theme, which again I say is brilliant in regardless to the nostalgia factor. Just because you, I, and other MM fans prefer MM3's Weapon Get to MM2's does not make the actual theme less nostalgic. Like I also said...
I mean, would anyone here complain or bring down the MM10 soundtrack if they reused the MM3 Weapon Get song?
MM10 really DID get more effort than 9, I'd say, though you make the valid point that whether or not that yields a better end result is a completely different argument. 10 harkens back to 2 with remixes rather than rehashes (minus the weapon screen which is original), overall delivering a more pleasant sound while still sticking to the NES instruments. 10 also delivers a greater variety of tracks (boss battles, special stages, challenges). In particular I appreciate the variety of boss themes, which I think is important for MM developers to keep up. They often get lax in that department.
I'm not disagreeing with you that MM10 has more effort put into it. It clearly does deliver a greater variety of tracks because it has more content in it (IE: More Special Stages, different character's shops, an extra Wily Stage, etc.). MM9 had one special stage in FakeMan's stage, which had an awesome track, plus the Endless Mode, which again had another fantastic track. As for the variety of boss themes, I've argued before that I think MM2's Boss Theme is SO GOOD that there was no need to use another. However, that's a matter of opinion. Personally, I think MM9's Boss Theme was going for that MM2 "It's so good" aspect as well, cept for the MM9 Wily Boss theme which still is the best Wily Boss theme ever, in my opinion.
And see, here's the thing about 9's throw-backs: If you're going to re-use MM2's soundtrack, there are INFINITELY better tracks to use than boss intro, victory, and get weapon, all of which are among 2's weakest musical moments. The boss intro especially is a head-scratcher to me, since that is in itself a rework of 1's. Just off the top of my head here, applying 2's Robot Master battle as 9's Fortress battle (especially as opposed to 9 not HAVING a Fortress battle theme), would have worked a lot more wonders than 9's current batch of attempted nostalgia.
Okay, I'm kinda lost that you'd think that MM2's Boss Intro & Victory theme are among MM2's "weakest musical moments" for a few reasons...Boss Intro
MegaMan 4 (Couldn't find a link to it)
(Didn't feel like linking these)
MegaMan & Bass
Marvel Vs. Capcom
I mean, personal opinion aside, MM2's Boss Intro & Victory themes have been used in a lot of MM games, so it's not just a matter of nostalgia, but more that they've become somewhat staples in MM Music. Yeah, I like the fact that MM10 remixed them to sound a little different, but it's still the same basic theme.
Also, in further defense of MM9's rehashing, it's not like they rehashed a lot of themes here, or anything of super importance. Lets see, the Menu, Game Over, Stage Start, Victory, Weapon Get, and Wily Castle intro. 6, count them, 6 themes out of 33 (I'm not including the SE's stuff). That's about 1/5th of the soundtrack, and considering that these are not really major themes here (as in not as memorable as the Opening, Title, Ending, Stages, Wily Stages, Boss Themes), and that these are tracks that last about 5-10 seconds, I don't really see the big deal here. It's meant for nostalgia purposes.I'm actually really glad they used the "lesser" tracks in there rehashing of MM2's music, because I'm glad they didn't give us the same boss theme, same stage themes, or same Wily Stage music (despite my love of them). These are the tracks I remember most from MM games.
