Why Oh Why Do I Feel this Way Lyrics

I was having a good-time sleeping this morning, feeling so lazy waking up, and suddenly I heard a song a very nice song with a very soft melody, it find me so attached with that song, and I was thinking this is the song I search most of the time looking for its lyrics, the chorus says "why oh why do I feel this way", and I thought that it would be its title, but I was wrong, its was actually the featured song from the primetime drama "Agua Bendita" by ABS-CBN channel 2 played by Six Part Invention(SPI) which is "falling in love" next to their known songs "all this time" and "umaasa lang sa'yo".
