Truant, I love that one so much, ill have to download it!! i really like the cartoony ones as i can showcase my favourite characters as i listen to music its soooo fun, i currently use the flandre one i linked below.
i love WINAMP (✧ω✧) but i don't download the custom skins from the internet library because i can't resize them to be larger for some reason, so i use the skins that are already included with the application. really cute software
