But absolutely welcome, and not the worst for being such and old song.
It makes an odd but even more oddly fitting transition to a much more lax portion at 15 something seconds, and then changes again to a half assed industrial theme that fits perfectly well in a sewer as well as making this song just subtle enough for ambience. It's main instrument or something, that odd synth like sound i guess fits well with the scale movements and carries your melody graciously.
There's plenty of space for more complex and riveting music but this song simply easy to listen to, music that wont effect your heart rate. It's actually great considering how old it is, creative, has a nice choice of instruments, relaxing even, which is out of many people's tastes.
