I was a title card video compilation of the Fairly OddParents and I saw it in the early 2010's most likely. It started with a soft acoustic guitar then a piano played in sync with it making the beat a bit higher. And then what sounded like an electric guitar started solely played for a while then a xylophone with the same melody played and then it was the acoustic guitar again but at a faster pace. Then it just kind of repeats. It ended after 4 minutes while the compilation kept going in silent.
