One of my favourite songs is "Hold On" by US girl group Wilson Phillips. It was released in 1990 and became a big hit all over the world. The song always cheers me up and the wonderful lyrics have helped me through many dark times!
"Hold On" is taken from their debut album "Wilson Phillips", also including the beautiful singles "Release Me", "Impulsive" and "You're In Love". I'm usually not a big ballad fan but Wilson Phillips' ballads are an exception!
If you're interested, you can find their album on iTunes and Spotify.
