It depends on the decade. Being a teenager in the 90s I have to go with Nirvana and Oasis for that era. I saw Oasis live four times, not in their prime though. Only in their later years.
I feel old now. I do not have much idea about today's music. I mean I do have Spotify but it is just not the same as back in the days, if you know what I mean.
Right now I would say Zara Larsson 'Never Forget You', Justin Bieber 'Sorry.' & A little bit of Drake.
