I learned a lot from disecting MSX music, especially the more complex songs in Snatcher/SD-Snatcher, the easy-going music in say Dragonslayer VI and the pure melodic 'carrier' in most 80s Konami and Falcom music. So I can't say I am influenced in my compositions by MSX Music per se (you won't hear any existing song in my own songs), but I did learn a lot from MSX Music.
My list would look a bit different btw
If I'm happy I make whatever I feel like making
If I'm in love I write piano ballads
If I'm sad I don't make music at all
If I'm without inspiration I make arrangements (and get inspiration that way)
If I'm lazy I'd make Trance or Dance music
If I'm overestimating myself I write epic orchestral soundtracks
If I'm practically braindead I would make hardcore or metal 
Yes, metal is very braindead music. Any child or idiot could make it. o_O
The same holds for trance (repeat-repeat-repeat-repeat-add extra tjikkaboom-repeat-etc) and ballads (piano, simple chord scheme, violin pad, prego)
If I'm happy I compose all kinds of weird tunes,
If I'm in love I have better things to do than compose music,
If I'm lazy, I just watch some telly, *hihihi*
Hehehe. 
and ballads (piano, simple chord scheme, violin pad, prego)
..sounds like the sad-letter tune from Fray to me
..sounds like the sad-letter tune from Fray to me That must be one of the first things I ever arranged.
It's in Xak 1 and Xak 2 too, by the way.
