I use maemo-scrobbler. Through Settings you can configure lastfm or librefm. It works through MAFW and scrobbled this morning

Media Player or better alternative Open Media Player scrobbles to lastfm.

If you prefer directory based player with scrobbling support, you can try RockBox. I've used it for many years (less RAM usage than MP/OMP), but got tired with manual scrobble import through QtScrobble
