The title track 'Sentimental Journy' starts off with some low soft drum beats which mimic the beating of a heart, which then slips right into the bitter-sweet melody and YUKI's super meloncholy vocals. All throughout the song the bassy chords and drum beats serve to remind us of the beating of our own hearts and YUKI spins her lyrics in a sad yet hopeful tone. The cover is a teaser for the 'Commune' album cover.

   The coupling track 'arigatou' is soft and soulful, kinda jazzy, slightly funky with soft, groovy guitar, this track sounds like perfect lounge room music. A 'choir' of 'ahhh' sounds are constant in the background giving this song a smooth quality. The chorus is sung with a certain "dubbed over and over" effect making this song sound a bit vintage sounding. This is a single to relax too.

   The second coupling song '17sai' is also a bit vintage sounding, but in a different way that's difficult to place. YUKI's vocals start of with a mature-sassy, growly tone that was made famous by... someone I can't place either. YUKI clearly had fun with this song, and it's a joy to listen to. She also throw in a 'dabidubi da' for old-time sake.
