I am in a cover band, and had a weekend off so I checked out a friends band, They were not very good, need some rehearsal but didn't have me running for the door. They seemed to play a lot of songs my band refuse to play ( I would play them but I think the guitarist and vocalist hate them death). Examples: Kryptonite, My own worst enemy (lit), When I come around, Good ( better than ezra), Talk Dirty to Me, She Hates Me. You get the idea. It made me wonder if they picked the songs based on ease of playing them or if they just thought they were good songs. I personally have no problem with these songs, if the harmonies are done correctly and people don't miss the nuances, but many bands just play them badly.
