I don't make playlist often, but when I do it I used Winamp's playlist.
Lovemusikku: All my favourite songs from my whole music folder (don't pay attention to the stupid name
)
Brezza d'Estate /
Summer Breeze: I usually make a season playlist. This time I put all the summerish songs in it.
RockSouls: Ayu rock songs and Diru's songs. I noticed that they sounds great put together.
