Honestly, having a bit less effort into it would still be better than not voting. Both for the organizer as well as for people who voted on, in this case, the Lithuanian song. Then if motivation is still an issue next time, you could consider not participating, but registering a song and then not participating is always a bit of a bummer (definitely not trying to sound harsh or 'attacking' at all, just to make that clear, I know if there's anyone out here who would never 'disrespect' TISC it's certainly you ).
