If you mean whether the cart music transfered to cd sounds better on cd format, i'm not sure.........but most of the arranged music on the cd's blows the cart versions out of the water.
Some of the music sounds the same (ex: Viewpoint) between the two versions (cart and CD), some of it has been remastered (ex: Pulstar.. the CD sounds cleaner and has added depth over the cart, but the tunes are the same), and some of it has been completely remixed (ex: Twinkle Star Sprites, the basic underlying tunes of the music are the same, but the CD's OST production quality takes full advantage of the medium).
There doesn't really appear to be any rhyme or reason behind which games were straight transfers, which were remastered and which were remixed (although, it would seem that most were remixed).
And just so you know, TSS suffers from a lot of slowdown, period. Unless you're playing the DC rev with the processing speed set to DC (instead of 68000-10MHz or MVS). Both the Saturn and PS2 versions of TSS also have the slowdown.
However, Pulstar seems to suffer more slowdown on the Neo CD than on the cart. I noticed this heavily in stage 7: if you watch the video of me playing the stage during the credits, you'll note that most of the time, the game is running at half speed. Recently playing the MVS cart, I've found that the very same stage suffers from very little slowdown. So I guess this is a result of how intensive the game program is on the Neo-CD's memory and how well the game-code is optimized by the division who did the cart-to-CD conversion.
