I, honestly, didn't find anything annoying. I actually liked most of the music, with the exception of some songs. Apparently, people are slamming Twilight Princess for using a MIDI sequencer, rather than orchestrated. I don't think it was just due to the lack of time for production, but also the GameCube discs could hold only 1.5 GB, not enough to hold a massive game and a recorded OST. However, I must admit, the synthesizer was pretty nice sounding.
Phantom Hourglass didn't have the prettiest of game OSTs, but I thought there were some nice themes to it. I did find Oshus's theme, as well as Linebeck's theme nice sounding. It seems I'm the opposite of everyone, because I thought the village theme rather annoying. I didn't mind the Ocean theme, but it wasn't as great as WW's theme. You got to remember, it is a DS. You can't fit a great synthesizer in 256 MB. Of course, they could've tried getting a synthesizer from the N64 *cough64bitzeldacough*.
By the way, Basement, Super Mario Galaxy did have some MIDI, but they mainly did the ones in which a certain sound could be achieved by synthesizing, and not just an orchestra (Bouldergiest, for example, was synthesized).
Back on topic, I thought that the MM soundtrack was the most disappointing. They had a lot of nice sounds, but the music couldn't top it's sister game, OoT. There weren't many songs that I flip for on my iPod (Yes, I'm a game music collector. Deal with it!
). The songs in MM were more emotional than OoT, but I thought the dungeon tunes were a lot better than the area themes (Snowpeak, Great Bay, and Southern Swamp had terrible, annoying themes). Then again, you're listening to a band nerd, so sorry for my ranting. [/rant]
Yep, I gotta steal a joke.
