Listen to a 50-70 bpm song (a real one, like the few ballads between DDR and IIDX and not bag, which Konami changed to 130 for IIDX) and then to something rated in the 120-130 range (a lot of DDR/ITG stuff), you may notice that the sounds occur twice as fast in the song rated twice as fast.  Be in my Paradise has 16th note runs if you claim it to be 63 BPM, halving that value so that a song twice as fast (the 120-130 range) fits with what you just said would make those into 32nd note runs, which are extremely uncommon in music from the sheet music I've seen.  Beats per minute follows the quarter notes and most songs in DDR reflect this on heavy; the charts are based around 8th notes with few rests exceeding one beat and only occasional 16th note work (normally.... So Deep and Grad Cyber are obvious exceptions).  There's music up in the higher range that isn't speedcore, though it is a little less common than DDR would have you believe.

As for speedmods being cheating or not... it really is a just tradeoff between spacing and time on the screen for the arrows.  Yeah, it ruins bag (most people still learn to 1x it at some point), but that's Konami's fault for rating songs independently of speed mods after they'd been implemented.  Having the arrow speed proportional to BPM was a terrible move, since it actually makes the faster 9's (the 170-200 range) easier to time than those slow songs that ended up as 6's and 7's on 1x for a lot of people...  I really prefer GFDM's style of having the speed be consistant and making the player figure out the timing on his own.  Also, anyone who claims that speed mods are unnecessary or cheating hasn't played much IIDX (where it's even encouraged by having the option menu appear as soon as you put money in and giving it a useful spread of multipliers [jumping from 2x to 3x doesn't give a huge dead zone, but the jump from 3x to 5x makes the 110-130 range terrible for me and I'm sure others have their own ranges like that], rather than the hidden option menu [and arrow codes, pre-Max] in DDR).

I voted hate.  

All they do is make people bitch about something useless. If they had never been implemented in any similar game ever, all people would do is wonder what would happen if arrows went faster or slower and then implement them in sims.  The fact that there are multiple implementations of speed mods (increments like IIDX vs DDR vs ITG or scroll rate like GF/DM vs everything else) just makes this worse.

I thought you ban people for philosophical/rhetorical posts.  Way to go.

nor do I...
x2 is my favorite speed mod. use it on every song below 225 BPM, and just x1 the faster stuff. I'm a x1, x2, or x4 type of guy, can't stand x3 or x1.5, cuz the arrows get spaced weird. BUt speed mods can both make a song easier (try bag on x3. now try it how it was MEANT to be played on x1. see?) but it can also make songs harded (Max 300 on x5 plz!)
oh that's another point I want to make. THe only time when using speed mds is cheating, is WHEN YOU ARE PLAYING BAG ON HEAVY! Totally defeats the purpose of the songs, and turns it into a 9 footer IMO.

UGH THE X COMES BEFORE THE NUMBER. 1X IS WRONG. X1 IS RIGHT. EXCEPT IN PIU BUT THAT DOESN'T COUNT.

GET IT RIGHT.

k, play DDR, open up the mod menu, does it say 1x or x1? 1.5x, or x1.5
there. finished.
also, think of it this way, instead of 1times the speed of the song, you could do BPMx1 BPMx1.5, BPMx2 etc. The BPM of the song is implied, it just multiplies by two, not the other way around.

I'm a badass admin speaking in the name of logic blah blah

How do you reason from there that I claim that anything that causes debate should not be included in the game?  I made no such statement.

I said I don't like speed mods because it gives people a reason to bitch about something.
