The band called Abe Vigoda (who were terrific) covered Stevie Nicks’ ‘Wild Heart’ and it’s one of my favorite covers: https://www.youtube.com/watch?v=Yhlf_GZAgk8
Another good cover is Haim’s cover of Tame Impala’s ‘‘Cause I’m a Man’ (technically a remix but they completely redo the vocals, which is why it’s good). https://www.youtube.com/watch?v=3J2I2huV6lE
Other favorite covers:
• Pet Shop Boys — Always on My Mind (https://www.youtube.com/watch?v=wDe60CbIagg)
• Scissor Sisters — Comfortably Numb (https://www.youtube.com/watch?v=SqIQzNNK9d0)
• Flock of Dimes & Sylvan Esso — Don’t Dream It’s Over (https://www.youtube.com/watch?v=wqOGc9ejEXA)
Annnnd some absolutely perfect covers I never want to hear again: José González’s ‘Heartbeats’ and Israel Kamakawiwoʻole’s ‘Somewhere Over the Rainbow’ and Gary Jules’ ‘Mad World.’ 😅
