Depends.
There's two types of music fans.
There's people who listen to shitty music, because they honestly think the artists are talented. This is the clueless music fan.
Then there's people who listen to shitty music, but can tell the difference between actual good music and bad music.
Because honestly, who isn't guilty of having bad music in their collection? I'm listening to REO Speedwagon right now - are they good? lmao, gtfo. You can either tell the difference or you can't - either way, who cares? It's your life, enjoy it.
