hullo all, been playing a decent amount and i would really like to work up my tremolo picking. something along the lines of the slide in Little Girl by DFA.

any tips besides sitting here beating my brains out with a metronome? much appreciated in advance.
Here is a suggestion- find a song you like with an EASY single noted bass line. Then tremolo pick to the tempo of the song while playing the song's bass line. It should be funner than beating yourself to death with the metronome.
