[TITANIC]

hi guys. i wonder if you have favorite song never ever get old.
you only can list 5 songs you think you never get bored after playing sooo many times so it's gonna be hard.
if you play a music in random setting, these 5 songs you will never skip it

I have been thinking for this whole day what 5 songs I never get bored and I have found that :

1. Koda Kumi - TABOO (2008)
2. Britney Spears - ...Baby one more time (1999)
3. Ayumi Hamasaki - M (2000)
4. SPEED - Body&Soul (1996)
5. Spontania Ft. Yuna Ito - Ima demo zutto (2008)

I never skip Ayu's M and mirrorcle world too but the opening are too boring sometime i fast forward until the chorus part so I dont put in my list
