User blog comment:OtterJiang/Playlist Update - Notable Luka Songs?/@comment-5027404-20141231011014

Well, I really enjoy:

Afterglow

Toluene

Blackjack

The CosMo cover of Melt

A.C.A.P (not notable but still really nice)

Some of them are sorta older than 2012 but many people do still like them. Most of the songs I would sugest have already been listed but you can always check out songs featuring Megurine Luka page for a whole bunch
