Can't say I agree, I don't mind the style of the new tunes per se, they just don't fit the general Lemmings vibe; Lemmings is not such an athmospheric game.
Haha, for someone who disagrees, you sure do point out a lot of stuff that's precisely what I hate about the new music.
I suppose I could be overreacting a little and am simply biased due to familiarity with the old music. Also note that I still think the music is well-composed, which is why I say I wouldn't fire the composers but would fire the "music director".
I know I'll probably get shot down for it, but I'm the one who voted for the Crystal music. 
I understand completely where people are coming from about the PS2 music, but the way I see it, we know we all love the old tunes so why vote for them when other unique ones are included too?
Well I tried to give the new music a chance. I did listen to all the music we can vote for, okay maybe not the full length of each, but I think I gave each music at least 15-20 seconds worth of listening. I may be biased towards the old tunes, but I honestly cannot find much I like about the new ones. And actually, in my notes I did jotted down earth 3 and hell 3 as two that are more tolerable, and for some reason, crystal 3 (even though right next to it I put, in parenthesis, "sleepy"?
)
I just remember enjoying the "mood" the music generated for me when I was playing PS2 Lemmings for the first time.
That's not a bad point actually. Perhaps the music simply makes a bad first impression on me, but might not be so bad when I actually play the game and they play discretely in the background. Then again, I tend to tune out the music completely anyway when my mind's focused on the level solving and execution.
And I still think that music can be ambient and non-descript without being slow and sedated, which tends to be the sort of feeling projected by the new-style PS2 music, at least to my ears. Cut down on the over-lush orchestration, throw in rhythms (ie. percussion) with a little more energy, and speed up the tempo a little, and I think it'd make a noticeable difference to my ears even if you keep the music ambient and non-descript (ie. no prominent melody/"tune" to speak of).
I like some of the PS3 Lemmings tunes too. Heresy! 
I know I'm in a minority, but across all the versions of Lemmings I've played, I like different tunes for different reasons. Heh, I'm not called "weirdy" for nothing, after all...
Well, if you can point me to the PS3 tunes I wouldn't mind giving them a listen and see what I think. I emphasize that it's not simply a matter of old vs new for me when it comes to the PSP/PS2 new music, it's the fact that the new music goes in a direction that I simply do not like. As a comparison, Lemmings 2 have totally different music from Lemmings 1 (except for Classics tribe), yet I like many of the new music in Lemmings 2 (in fact if I were to vote on the Lemmings 2 music, I probably won't vote for the Classic tribe even though it's a well-done rearrangement of 2 tunes from L1).
Can Can is actually not bad, but I agree on She'll Be Coming Round The Mountain.
Funny, I kinda go the other way. I can see geoo's point with Can Can as I find it, surprisingly given the new tunes,
too energetic (though perhaps it could work with a more frentic level with lots of multi-tasking, or a short time limit). But I thought the slightly spiffed-up version of "Mountain" wasn't so bad; I'd pick it over Old Tune 3 for example.
