Have you been keeping an eye on your favourite artists' Twitter accounts during the COVID-19 crisis? If so, you may have noticed the hashtag "utatsunagi", which translates roughly to "song connection" or "connected through song". Artists will post a short video of themselves singing or playing part of a song, then tag another musician they'd like to see do the same.As countless tours and concerts have been cancelled to help minimize the spread of the virus and many musicians find themselves at home with some unexpected time to spare, this trend has quickly spread through many different scenes, with both mainstream pop artists and lesser known indie acts taking part. Artists have used this hashtag as an opportunity to tackle tracks by groups they admire, to cheer fans up by covering classics by their own beloved disbanded or inactive bands, or even to share brand new songs from their current projects.For readers who aren't regular Twitter users, we've compiled some of our favourites below:, vocalist of rock bandSinger-songwriter, vocalist and guitarist of rock band, solo artist, and former frontman of, vocalist of folk duo, frontman of rock bandsand, performing with members of, solo artist and vocalist of rock band, one of the MCs from hip-hop group, a popular anisong artist:, one of the vocalists of rock band, solo artist and a member of alternative idol unitHas your favourite artist taken part?
