I liked a couple of the songs, but most I'm like "ehhhh" or "bleh."
The ones I like are "All Through the Night", THE SEA PONY SONG (best song ever), "Dressed Like a Dream", and "From the Sun". Also "Those Newborn Twins" and, surprisingly, "Babysitting".
Who else remembers the song "Hurry"? It was sung in a segment where Megan, the ponies, and the bushwoolies weave a fake cloak for Porcina in "The Glass Princess." But when MLP & Friends aired on the Disney channel, it was cut out. Sadly the song is still missing in the boxed set.
