Tune
Piece Of Music, Song, Melody
counter, independent noun, in compounds
This almost shares the meaning with the kanji. It's essentially the same thing, though when it's alone it refers to a specific piece of music (aka a tune).
The reading is the same as the one you learned with the kanji as well, so you should be able to read it.
この曲はアメリカで人気です。
This song is popular in the United States.
おすすめの曲はありますか？
Do you have any recommended songs?
このロックバンド、曲じゃなくて見た目がいいんですよ。
What's great about this rock band is not their music, but their looks.
