There aren't many favorite that are release, but at least I found the OP song of Sengoku Basara really catchy even though I haven't watch the anime itself. Other than that, Hetalia song is quiet good too along with K-On! with fluffy lightly style. Toradora album is also release during this time. Many good song on the album I could say.
