"22" is great. She could do no wrong that era - great string of singles. "I'm Not the Only One" is good, but all of Sam's music from his debut era has aged poorly for me.
"Glad You Came" is a summer anthem I'll never forget. "Too Close" is also a memorable moment for me. "Price Tag" is Jessie J's best song. "Burn" is one of the few Ellie singles I really like!
